I'm aware a lot of people can't do that, because their personality consists of being of a certain ideology and they cannot shut up about it, but it's technically possible to just have a normal-ass presence online without pushing opinions or ideology beyond professional/technical ones.
It's very simple -- this stuff is private. Your political opinions are private. Your social opinions are private. The internet isn't private.
Talk to your friends about that stuff, in person, instead.
Why? What should we talk about instead as members of a polis? About endless consoomerism and other such hedonistic stuff?
all these could be considered political. In my opinion they often are inherently political.
science: evolution debate, climate change debate, who gets studied, what gets funded.
facts: statistics (and who makes them), places names and borders (gulf of mexico vs america), textbooks (how is the history of slavery thought)
games: censorship rules, didactic games, regulation in games, content and representation of mainstream videogames(evil brown terrorist vs good guy US marine)
art: patronage, "degenerate art", monuments and their legitimacy vs their removal, looted art, protest art
music: folk and protest music
hobbies: cycling (any comment on bikes degenerates to a car vs cycles debate), DIY (right to repair, 3D printing regulation, open source culture)

Right Wing Extremists in Germany are those who argue that citizens aren't really citizens because they are brown and need to be "remigrated" (despite Holding German citizenship, or even "native Germans" with the wrong political views)
They also want to use Military Weapons for this
And those who deny and continuously try to minimize and deny the crimes of the Nazis in WW2.
But somehow those right wing crybabies are also always poor little babies that are just misunderstood and the perpetual victims.
