why do u all love blondes so much??

its like a girl can be a 4 but if shes blonde she becomes a 7 in your eyes. and if a dark haired girl is an 8 she becomes a 7 in your eyes. why do u all love and favour blondes so much???? and DONT say personality bc no way on earth is that the truth. js be honest why do u like them so much over everyone?
