the elitist douche is anyone who looks down upon someone for any reason.
my metal is more true than yours. (look at the back/progressive/whatever crowd for proof)
my amp/guitar/pedals/cables are better/rarer/more expensive/more brutal/louder/whatever than yours.
my posts are more researched/thought out/better worded/punctuated/spelled/whatever than yours.
my dick is longer/thicker/stronger/smarter than yours.
my girl is hotter/taller/better job/bigger tits/tighter va-jay-jay/whatever than yours.
in some way, we all have a little elitist douche in us. i see some crack whore blowing truckers for $10 and think "UUUGGGHHH!!!", and thank the maker i never fell that far (as far as you know, anyway).
i can walk into most music shops and will rarely see something i want. in a way, that makes me kinda elitist. and it's not that the gear available isn't nice, it's just not what i'm looking for. in reality, i have all i could ever want or need. but, it only works for me, and that's all that matters. if what you have works for you, then that's all that matters to me too.
