Why do men always say they prefer brunettes...?

my favorites are in this order Redheads Brunettes Blondes and girls with black hair, i prefer redheads becasue redheads are just plain hot i dont know why they are but they are, brunettes are very attractive and i love the way that a brunettes hair feels while i run my fingers through it blondes are nice to look at but i look at brunettes more then blondes and if a redhead walks in all bets are off for the brunette or the blonde
