Ignore the surplus

Spoken like a true Marxist

Value was taken away from those who needed it (example case holomodor)

You're telling me that the first attempt in history at collectivisation of land wasn't perfect? Damn, communism destroyed. Fyi, land collectivisation was carried out by poor farmers, and they were so bloody and excessive against Kulaks that the party had to go and impose limits on how many people were declared Kulak per region. Holodomor was a tragedy as a result of a poor first attempt in history at land collectivisation, not an intended extraction of value of workers from a given place at a given time, as proven by the fact that when land collectivisation ended, nothing like that ever happened again.

Especially in occupied areas, non-russians were treated as 2nd class citizens and partially eradicated (insert "go to gulag" -meme. See also: genocide)

The Stalinist terror can and should be condemned. It was senseless, excessive, cruel, inhumane, and worst of all, unfounded and pointless. But trying to add racial/ethnical undertones to it is ahistorical. It happened to Russians and Georgians and Armenians and Uzbeki alike.

So quick online search already shows you that it had nothing to do with equality between the men and women, but about better abusing women's labor. Just like in a capitalist society

Sure, that's why women would retire at 55 compared to 60 years old for men. That's why there were widely available restaurants and canteens in cities and food service in workplaces to relieve women from the burden of cooking. That's why there was a wide availability of kindergarten to rid women of the burden of child rearing. But oh yeah, you did a quick online search, which totally proves that feminism in the USSR was actually not true feminism somehow!

While propaganda claimed, accurately, that more women sat in the Supreme Soviet than in most democratic countries' legislative bodies combined

So wait, you're telling me, that the country with more women in the Supreme Soviet than in basically the rest of the worlds' legislative bodies combined, wasn't pioneer in feminism? I'm not saying it was feminist to 2024 standards, or that it was perfect, but it was by FAR the most progressive country on earth at the time.

Your ideas don't mean a shit if your actions don't reflect it

The USSR was the only country to sell weapons to republican Spain (I'm Spanish) in their struggle against fascism. They provided immense help to China in its early industrial development through technological exchange and sending experts to their economy, as they did with most other socialist countries at the time. The USSR was a beacon of internationalism in an otherwise capitalist hellhole of a planet. Key note in internationalism, the USSR itself had an incredible national diversity between its republics, with most people in central Asian republics not even speaking Russian after 7 decades of USSR. Industrial development being boosted in the poorest republics such as Central Asia, equal access to medicine and healthcare in all republics, education being provided in the local language of the republics... Fuck me if that's not internationalist solidarity as opposed to nationalism.

The unions were led and controlled by the communist party

If unions were so bad and useless, but voluntary to join, why was the USSR the country with the highest unionization rate? The myth of "they were controlled by the communist party" is, well, just a myth. Some things that Unions did: Controlling important aspects of production. Enforcing workplace safety regulation. Organizing educational activities for workers by workers, and training for higher positions. Providing access to doctors and medical revisions. Providing access to affordable housing. Choosing representatives to make their demands. Electing higher positions within the workplace. Providing announcement boards and periodical publications with complaints and remarks of workers for everyone in the workplace to read.

Insane that you think the workers weren't exploited for the surplus value they created in the USSR. I guess the holsum state apparatus just took what value the workers produced

You trying to justify that a society can exist without any degree of bureaucracy, and somehow the existence of administrative personnel earning normal wages totally means that there's an oppressive class and an exploited one.

and then very conveniently gave them the amount it was worth in incredibly shitty housing, bread lines

Hahaha oh god no, "communism is when bread line and your house is ugly". We're at peak lib levels here. Bread lines were nonexistent in the USSR after WW2 until Perestroika, but sure buddy, you've done your research.

no mass deportations and genocides of ethnicities inconvenient to the Russian majority

you run a colonial empire

You're a fucking joke. You can possibly make the argument of forced deportations of Crimean Tatars, but that's literally the only case of anything remotely like an attack to a given ethnicity that you can conjure. Saying that there was anything remotely resembling genocide in the USSR is ahistorical anti-communist bullshit. Again proving you haven't read a fucking history book not written by libs. Oh, the russian majority, adoring a Georgian as a statesman and leaving as his successor a Ukrainian! There hasn't been a single state on earth less oppressive towards local ethnicities than the USSR. Education being offered by law in the regional language of the republics, written publications in the local language exceeding that of Russian in most republics, celebration of local customs and traditions (go to Uzbekistan and tell me how Russified they are), equal access to education, healthcare, similar salaries between republics and ethnicities, vast investment in industrial development of all regions... You have no fucking idea what colonialism is.

Women's rights were world pioneer levels in the USSR. Hah. Maybe in the 20s

By the 70s, there were more engineer women in the USSR than in the rest of the world together. You can't at that period find comparable numbers of women in justice, in higher positions at education, as doctors, or as any highly regarded position in society in literally any other country of the world, not even those that had been industrialised for 150 years longer than the USSR. Widely available canteens and restaurants so the burden of cooking won't fall on women. Widely available kindergartens so that the burden of upbringing children won't fall on women. Again with the fucking ahistorical bullshit. Claiming that the USSR was the most feminist nation of its time is simply a historical fact if you look at any fucking statistic on the topic, which you clearly haven't done.

What good is a union that doesn't even have the right (or ability) to strike?

Controlling important aspects of production. Enforcing workplace safety regulation. Organizing educational activities for workers by workers, and training for higher positions. Providing access to doctors and medical revisions. Providing access to affordable housing. Choosing representatives to make their demands. Electing higher positions within the workplace. Providing announcement boards and periodical publications with complaints and remarks of workers for everyone in the workplace to read. Again, proving you haven't read a fucking book. I'll flip the question: if unions were useless, why was the USSR factually the country with the highest number of unionized workers? Did Stalin personally go to everyone's house and put a gun to their head to join the union or what?

Not leftist anti-Stalinism

Nuanced anti-Stalinism is actually good, I'm not Stalinist by any means. The great terror was absolutely horrendous, unnecessary, and accomplished nothing. But the extent of the analysis of Stalinism being "this happened because Stalin bad" isn't Marxist, it's lazy and peak lib.
