I wouldn't "pretend" to be political just to fit in. Pretending you think or are something just to fit in just ends up with those relationships feeling empty.
It's understandable to be hesitant to bring up one's political beliefs in general, let alone if everyone around you seems opinionated and self-certain. If you're worried about them pouncing on you for saying something "wrong", then you might want to reconsider hanging around these people. If they're judgmental and performative, they might just not be the best people to hang around. It might be a good idea to try to talk to a member of this group that you feel most like you can trust--or at least one you feel won't judge you for being politically uncertain. If you still worry, remember: none of those people were born leftists; they decided on their beliefs most likely gradually over several years; many were raised to believe socialism is straight up evil and only changed their mind recently; some of them might be hesitant like you, but do not state disagreement or confusion for fear of backlash.
I, like the people you mentioned, am also a queer commie/anarchist. Socialism/communism/the left in my experience appeals to more queers than capitalism/conservatism do. There's no shortage of exceptions though.
If you're politically uncertain, then do some research. I realize that's easier said than done but yeah. "Queer politics", "radical queerness", "queer socialism", or things like that would be good places to start. Or just try to have a patient, non-judgmental conversation with a friend. Hell, you could dm me if that works. I won't judge.
