I don't think that's entirely fair. I was once dismissive of stuff other people got deep into, things like horoscopes, or fashion, or sport. They wereen't relevant to my life. But as I've grown I realised how much this limited me, meant I was essentially choosing to dismiss those people and the things they liked as unimportant, indirectly insulting their intelligence.

I consider it to have been a character flaw of mine, and I have tried to work on it. It's not and never will be cool to take pride in not liking something other people like. They like it for a reason, and it turns out if you just shut up and listen enough you will probably start seeing the intricacies and come to like or at least appreciate it too.
