I can't speak about lemmygrad since the instances I'm on all defederate from it, but Hexbear users have a reputation for being generally aggressive, grating, and immature. It's like that kid in class who keeps interrupting the teacher because they think they're funny and clever. e.g., some were screaming at me that I can't be an anarchist and I know nothing about anarchism since I'm married, replying with third-grade tier memes for some confusing reason

They are hardline Marxist-Leninists, something that is very rare in the western world even amongst those who identify as leftist or socialist. If their views make you uncomfortable, then you're not a ML, which is okay.

Left-wing politics is a very broad spectrum, and a lot of Lemmy users lean towards the more moderate end which brings them into conflict with the more radical communities that are Lemmygrad and Hexbear.

That's all there is to it.

Lemmygrad and Hexbear aren’t “leftist” in the confused sense that Americans usually mean “leftist.” They’re actually leftist in the original sense, meaning that they want to abolish private ownership of the means of production. To the extent they’re “widely hated,” it’s largely because the Anglosphere has been indoctrinated against real, actual socialism their entire lives.

Liberals hate communists more than they hate fascists

If a communist isn't hated by the capitalist establishment, he isn't a real communist. (I do not imply that being hated by the establishment alone qualifies you to be a communist)

Lemmygrad isn't "hated" by most of the wider lemmyverse. There's just a loud and obnoxious minority of people that will rail and rant about lemmygrad. They loudly rant about lemmygrad because they aren't used to seeing their worldview get challenged and by its very nature as a radical leftist community, lemmygrad is a challenge to the typical background liberal perspective.

It's no surprise we all end up seeing a lot of threads about "those mean tankies at lemmygrad" (and hexbear too) made by people who can't take their worldview getting questioned, or even shown to be flawed, or just not standing up to their own scrutiny, and who get mad when that happens. There are also of course people with ideological reasons to demonize leftwing politics and will spread shit for that reason alone. But overall, I don't think most people care enough except to think "oh yeah that's that instance with those radical lefties, they're weird but they do make some great memes sometimes."

Political views aside, the way they promote their political views is unappealing.

Look through any of their popular threads. Everyone piles on any comment which doesn't align perfectly with the agreed perspective.

Lemmygrad and Hexbear are cool. IDK why you wouldn't like them if you're a leftist.

I've been trying to find a good Marxist instance, but Lemmygrad and Hexbear are widely hated. Why is that?

Because the majority of Ledditors are either liberals or full blown reactionaries and the ones who are not range from some cringey techno-libertarian who think FOSS will usher in socialism to some radlib cruise-missile socialist who strangely never deviates from the US state department. The very few who could legitimately be considered socialists are some kind of anarchist. They certainly aren't Marxist.

Are there any good leftist instances?

Outside of those two, I won't hold my breath. The easiest litmus test in the world is how they're responding to the genocide at Gaza. There's very few places where you'll get complete support for the Palestinian liberation struggle and not whining about the imaginary babies Hamas allegedly beheaded or trying to equate the conduct of a genocidal nuclear power to a paramilitary fighting for national liberation.

They're both good instances. People have been heavily propagandized to hate communists. You could make the kindest most welcoming space on the internet and if you put the label "communist" on it, it will be hated.

Lemmygrad is filled with the American patriot version of communists. You will excuses for the Uighur genocide and acts of repression against ethnic minorities for the good of the nation as a whole. You also get into weird cases of trying to redefine words because the words don't match their narrative. For instance, I was in one discussion trying to argue that China was a democracy because the government worked for the people, even if there was never any official method of communicating the public will.

Hexbear seems more geared towards being angry and bitter at liberals for not doing what they see as the right thing. There isn't any discussion on political theory, talk of political organization outside of violent revolution is frowned on, and the focus seems geared on one small part of the political spectrum while ignoring other parts entirely.

If anything, solarpunk may be the healthier leftist sub because it is geared in part towards solutions instead of focusing on problems.

Generally, they aren't marxists, they're "tankies". And even fairly extreme socialists tend to dislike that. That's lemmygrad.

Hexbear is just filled with trolls that federated specifically to troll and disrupt the rest of lemmy in the name of their beliefs.

On either, you can find individuals that are perfectly cool to talk to. But it's like rolling the dice where only snake eyes win. And, even when you win, you can't be certain that it isn't a long troll waiting to fuck with you because some of them do that too.

I believe you've answered your own question.

Lemmy isn't Marxist-only. The majority of Lemmy users are what the more vocal Lemmygrad and Hexbear users deride as "libs." As a thought experiment, imagine that you are one of us for a moment and then browse Local on one of those.

Haven't seen any lemmygrad users in a while, but honestly the vitriol towards Hexbear is overblown. They're fine. Bit trolly, and they shitpost a lot, but it's kinda fun.

Liberals.

I'm the only person I've ever seen on Lemmy running an instance from a nominally communist country (maybe there are others?). You can come hang out with me I guess. I'm not qualified to be a proper communist though -- I've read very little of the literature, and leave politics to the Party. Which I am not even actually a member of. I'm basically Boxer from Animal farm, but ended up happily married and with a decent standard of living instead of shipped off to the glue factory.

I'm am a mercenary science hermit though, so my instance is very quiet! There are three people on my instance, two are me and the other is a bot I wrote doing I-Ching divinations using physics.

I haven't seen or maybe haven't noticed much of lemmygrad. But hex bear has a culture of spamming the same handful of images, using them like punctuation in their posts. And they show up huge in my reader at least (I just found out they look small to them.) So it's like you're trying to have a discussion and someone comes parading through with like five crappy drawings that take up all the space. Also I don't mind having Marxists around but they tend to want to steer every discussion toward it, regardless of its relevance. Can't wait to be able to block the instance.
