The stereotypical roles of females throughout history and time has been that females are, in fact, into beauty, hair, makeup, fashion, cosmetic surgery, skin care, fitness--basically, anything that BEAUTIFIES or makes one more SEXY! Thus giving sex appeal or making one more ATTRACTIVE, sexually desirable, or sex objects.
If you are into makeup, hair, fashion, fitness, skin care, cosmetic surgery BEAUTY PERIOD! you knowingly or unknowingly support sexism. Too many women support sexism, evidence of this is THE MULTI-BILLION DOLLAR BEAUTY INDUSTRY!
Sexism is a battle that can't be won. Besides, who doesn't want to be sexy and beautiful?!?
This is not to say that pursuing knowledge, information, or an education is a waste of time. Ultimately, in the long run, it is wise to be more than what meets the eye.
