That’s not what fascism is. We ban things as a society that are harmful for us. I’m sure libertarians disagree with that basic principal but pretty much everyone else doesnt

I don't think you know what "fascist" means.

Moreover, people will happily complain that Chinese/Russian "propaganda" is allowed to exist, especially on the internet. They will demand that Chinese/Russian "propaganda" is removed from social spaces. And, then they somehow they have a problem with other countries (esp. China/Russia) wanting to do the exact same thing. The premise is that the propaganda being put out is misrepresenting the truth to influence public thought: when it comes from China/Russia, people want it blocked and removed; when it comes from the West, blocking and removing it is some sort of "free speech" issue (or, as you wrongly claim here, "fascism").

In this particular case, I don't personally know hardly anything about the movie, and I do strongly disagree with using "promoting homosexuality" as an excuse to ban something. But in general, countries wanting to put a damper on other countries' propaganda is near universal.
