If it was up to me our industries would’ve never left the country in the first place, and most of the privatizations wouldn’t have gone through.

Alright, I see it the same way. Still, Germany managed to manoeuvre itself into dependencies of Russia and China, which has shot and still shoots them into the feet.
I'm totally in favour of trying to find diplomatic ways. But if the call to the talking table is not followed and rather met with aggression on multiple levels, it's usually the wrong way to give into the demands of the ones who are not afraid to use violence. Therefore, what you see as "funding aggression" is to me a display of resistance. It shows that we will not be bullied into submission, nor will we allow those who use violence to dictate the terms of peace or cooperation.

nazi like rhetoric going around nowadays. Green politicians talking about “the poison of Islam” [1], which reminds me a lot of the antisemitic rhetoric from WW2 (see “Der Giftpilz” [2]

I've read the article and watched the speech of Katharina Dröge afterwards to get a grasp of the context. As I've suspected, the article of the far-right magazine "Junge Freiheit" over-emphasized the "Gift des Islams" part of her speech. It's just typical click- & ragebait again and a very misleading headline. At least the article itself somehow manages to not completeley misrepresent her actual speech.

You'll probably notice as well that this was a rather minor phrasing. More importantly, it was embedded in and directed towards islamism, i.e., people radicalized to the point of becoming murderous, which has to be prevented of course. In the same speech she is emphasizing the importance of asylum for all of those who have suffered the worst and don't become radicalized criminals.
Given this context and the fact that the German Greens are usually considered a rather left-leaning political party, I find the comparison to 'Der Giftpilz' not only vastly misplaced but also ridiculous.

Besides that, Germany didn’t denazify properly after WW2 anyway (“Persilscheine”

Thanks for pointing out the "Persilscheine". Despite the tremendous amount of "Nazis evil"-content in school, especially in history classes, this wasn't a topic. An educational gap I'm eager to fill soon.
Regarding the statement of unproper denazification I can't add anything to that besides personal impressions which have no value for general statements.

The chancellor talking about “deportations in big style”. The CDU trying to ban refugees from going to any public events. And these are not even the nazis in the AfD. It might be 2024, but mentalities haven’t changed much, we’re just picking other out groups to stomp on, mostly because we’re not tackling the real issues at heart.

Yes, yes. This is indeed really bad. From my point of view the big old parties SPD, CDU/CSU are fearing for their public support. And instead of trying to address the real issues, they're mimicking talking points of the AfD. The latter, unfortunately, becoming increasingly popular in many areas of Germany.
I wonder why that is.
No, I don't.
(Okay, people being too incompetent to critically think about media adds to that.)

However, I wouldn't go as far as to say, that the mentalities haven't changed much in all that time since WW2. Three generations were raised since then with the fourth one reaching maturity. And there is still a tremendous amount of people who are not sharing the same xenophobic idiotism propagated by AfD, CDU & Co. It's not too late to prevent the mistakes of the past.

But again, to get back on China, Germany is very well conducting major business with a ton of authoritarian countries, stomping on workers’ rights all across the world just to enrich German companies, and thus I won’t take their virtue signalling for anything more than just virtue signalling.

I'm also not really happy about that. It's one devil replaced by the other. However, there are different shades to that. At least the one devils have not launched a full-scale war. And now Germans have started to question their dependencies on foreign countries a bit more. But of course it can't be a long-term solution to keep things as they are now.

I'll take virtue signalling. "It's something". Besides, the current government is the most productive since the Merkel-era and has initiated and achieved many good things. Although I agree that regarding foreign affairs it could be better. Most progress was achieved in domestic affairs.

I’m here just pointing out the hypocrisy. If they care so much about Taiwan, they should at least make it clear that it is due to geostrategic interests, not because they suddenly found their love for democracy and what not other nonsense.

And people love hypocrits. If someone says the one thing, but does the opposite, does it make them wrong in what they said?
How about we criticise the bad and praise the good?
