Do you tell your friends you're a communist or socialist?

I was out with a friend tonight, we were talking about darkwave music when she mentions a band making music with a "soviet vibe" (for a lack of a better term). She then says that the Soviet Union is depressing which is why the music is dark lol

I usually don't mention my politics to anyone, so I didn’tcounter it. My friends are liberal so we agree on some social issues. I don't want to jeopardise my friendships and usually we end up talking about other things. I don't have communist friends yet!

If you do mention it how do you go about it? Without losing friends?
