Why are men so stupid?

Why do men seem to always follow their dicks and not their brains? Nature or nurture? TV? Internets? Why the fuck are men so fucking stupid?

If men are so stupid than how can you even suggest that women are somehow smarter? I've met so many women that get drunk, sleep with guys they know for an hour, and get all sorts of diseases and never talk to those men ever again. The only reason men think with their dicks is cause they know thinking with their dicks has a good chance of favorable results, sex, because so many women are such sluts they give it away to any guy who's in a band or owns a nice car. Instead calling us stupid and whore-mongering how about you tell women to stop being such sluts all the time, then maybe we will learn some manners and restraint.
