Is anyone in the CS club?

I kind of wanna join but guys in computer science are always so judgey cause I'm kinda pretty or whatever and they always think I'm stupid... Just last week some guy said "To be honest, you don't look like you would know any of this stuff. I never would've thought you were actually smart".... so that's fun. Anyway, I keep convincing myself not to go but I kind of want to. I just don't like awkward situations. So what's it like, exactly?
