Probably the same reason you don't like the bands you don't like. Some people just aren't into this kind of music. But if you're talking about why they hate the actual people, who knows.
Because world´s crazy!! haha. I don´t think people "hate" GC, I think some people just don´t like them...maybe cuz they don´t like GC´s music, or maybe cuz they are deaf...or insane!!! haha jk.
I don´t care what people say about them, I´ll always love GC.
Those who say they hate GC..its their perogative to like/dislike them. Music is like art..not everybody is going to like the same painting or artwork! :) lol Some people may have moved onto other bands or genras of music. Some are jealous of GC too. I never listen to anyone who disses GC. I don't diss other people's choices of music/bands/artists because if everyone liked the same things it would be boring..plus I want to be able to get tickets to see GC! :) lol
