I hope you aren't referring to me. I spent 4 years in college with a roommate who listened to nothing but rap ALL FREAKING DAY. I've heard plenty of it. I think it's all awful, with the exception of one or two discs by artists who actually hired (gasp!) actual musicians to play on their albums.

I'm a 20 year student of music. I practice 4 hours a day, and have, just about every day, since I was 14 (I'm 31). I know all about generalizing genres as well - metal fans are just like rap fans in a sense. The rap/hip-hop/r&b/club/etc thing gets tossed around as black metal vs doom metal vs power metal, etc, etc. It's all just music. I can't stand rap. I also can't stand the Bee Gees, but at least they could read music before having the audacity to call themselves musicians.

Metal has some equally cheeseball stuff, but there are very few bands (actually, I can't think of one) who write entire albums comprised of nothing but odes to themselves, their crew, and how badass they are because they own a gun, drive a ferrari, or basically just hate.
