As a German it's fully in your right to disagree with the state and with the police (I certainly don't agree with everything that's going on). However, this comment of yours is distorting the reality too much, for my taste, to remain silent.
"terrifying state repression" = less public funding for some artists, more for others (not getting free money doesn't mean you're being "repressed")
"Berlin police has enacted checkpoints in immigrant neighbourhoods" = That did not happen. It is a myth.
"Politicians actively singling out activists on social media and redirecting insane amounts of hate their way." = Politicians responding in kind when you mention them in a tweet. They are humans and they are allowed to respond to you.
"to allow universities to exmatriculate students on behavioural grounds (aka political stances)." = Berlin trying to fix a legal loophole that prevents them from exmatriculating one student that physically assaulted a Jew for antisemitic reasons breaking his face bones. Outside of Berlin that would've been grounds for immediate exmatriculation within the existing laws.
I do agree with your general stance, but there is no need to exaggerate/distort the issues we're facing.
