What stops you Bud/Miller/Coors/Corona drinkers from trying craft beer?

Bud, Miller, Coors, Corona, Heineken. These are all crap and are all comparable with none of them standing clearly ahead of the other. There are 70+ styles of beer out there and you people will never know more than 1 (maybe 2 if you try Guinness- another crap beer by the way). My question is why are you people afraid to try beer that actually has flavor? Where I go if someone orders one of those macro brewed crappy beers everyone starts laughing at them and insulting them. Open your eyes! Now tell me what stops you.
