Why the hell is everybody so ist?

I don't understand this! it's so ******* stupid. And it's not just girls who are being undermined either. There are stereotypes that all guys are stupid, all guys like sports, guys don't have hearts ( they think with their ) etc. Women are apparently whiny, jealous, catty bitches who like money, jewelery and use to get what they want. It really pisses me off. why are people so stupid? I'm included in this too! Sometimes I find myself thinking that there's no way in hell that there is a nice, smart, interesting guy out there. I don't want to think this way. it's really ignorant and ignorance is disgusting. This isn't really a question: I just need to rant but I'd love to hear your thoughts on it. If you're a male, i'd also like some urance that I don't have to completely give up hope in your gender. lol
