You want to know what I watch? Anything. Sometimes I enjoy it - sometimes I don't. I certainly don't let what anyone else thinks stop me from watching a show. If I like something, I'll keep watching it until I get sick of it; doesn't always happen but if it does, I'll make the break.
Watching a show doesn't make you dumb, stupid, ignorant, bland or mean you have a bad or no sense of humour or taste. Neither does it mean that you are any of the things opposite to that. It just makes you a watcher of TV. I wouldn't not be friends with you just because you were a fan of The X Files. In fact, you'd probably need all the friends you could get anyway.
