"Politics guy" at work. I didn't ask to hear your rants, to see your articles or chain e-mails, to hear the biased political show you play too damn loud, or to see the crappy memes on your phone. If I want to hear your politics I'll ask you for input, otherwise the internet is full of places you can rant, link, and meme to your heart's content.
Folks that cop an attitude of superiority about what stuff they like or dislike. Snobbishness in general is obviously bad but this is probably the dumbest form of it.
