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?

The femenist inferiority complex is caused because humans, like all animals, naturally assign different roles to males and females which both parties generally agree upon; now, these crazy women decide that they want to have the men's role, but since they can't, they want to fight about it.  They can only explain their continuous losing streak by male oppresion, since their to stuck up to admit that they're just being stupid.
