Does this problem with so many people irritate anyone else?
I dont know how to explaine, so I'll just give some examples.

I go into a comic shop, there is some irish sounding death metal band on the radio behind the counter. I ask the guy what band it is, so I can check them out. Rather than just give me the name and let me go about my business he goes off about the history of heavy metal and how the metal that most people like is inferior to the obscure bands that he has discovered online. He then goes on to list off 10-15 bizzare sounding band names that he insist are the only things worth listening too. I try to contribute to our conversation by stating some equally obscure black/death metal band that I really like but he just won't have it, if he does they do not compare to his superior tastes. If not the idea that he hasn't heared of a particular band seems to terrify this guy, so he just disregaurds and goes on about how great [insert 20 obscure band names here] are.

This same thing happens if you mention Slipknot in a guitar shop, everyone in there will just treat you like crap. You go into the same shop a few weeks later and mention that you hate Slipknot all these same guys will bash you for not being open minded, or trying to make you feel stupid for "not realizing that other peple have different muscal tastes"

And countless other similar scenarios.
I've also noticed that normally clean mouthed people start using lots of profanities when they go into these elitist trances.

Who else have had run ins with these types?
