But America’s First Amendment seems to not understand that reason (or only understand when it is weaponized against communism, black people, trans rights and all the “woke culture” stuff)

Like alot of things in the USA, laws are selectively enforced to protect the status quo.

"Youre anti fascist? Youre a terrorist!"

America's first amendment doesn't grant a total right to free speech. Conspiracy to commit murder is just speech, but is very much illegal, and so is copyright infringement.

Germany make a strong stance against any “trolling” nazi joke/imagery/salute

And look how that's working for them: clamping down on pro-Palestinian protests as antisemitism, raids & arrests over calling a politician pimmel.

The 1st Amendment "understands" just fine. You don't understand and want a thought-police state.
