Welcome to the Internet.

Many forums (including this one) have bans on "politics" or topics that are "inflammatory". 95% of the time what constitutes either is simply "things I disagree with".

For US politics in particular, as much as the right-wing cries about being censored, social media in particular bends over backwards not to silence such views whereas anything critical of those right-wing positions gets flagged or downranked as being "political" (eg [1]).

Typically this process isn't direct. ML systems will find certain features in submissions that get them marked as "inflammatory" or "low quality" but only on one end of the spectrum. For sites such as HN, reddit and Tiktok, right-wing views have successfully weaponized user safety systems by brigading posts and flagging them. That might then go to a human to review and their own biases come into play.

As for France vs the US, I'm sorry but France is irrelevant. As we've seen in the last 2 weeks, what the US does impacts the entire world. All the big social media sites are American (barring Tiktok) so American politics impacts what can and can't be said on those platforms.

Twitter has become 4chan, a hotbed for neo-Nazis, racists and homephobes.

And which French politican are we talking about? Marine Le Pen? If so, the relevance is the rise of fascism in Europe between National Front in France, Reform in the UK, AfD in Germany and, of course, Hungary.
