Madonna has a new mission: to end ageism. And women everywhere should back her up on this. Madonna is 56 and she endures horrible insults because of the way she dresses. She says she has no intention of changing her style because she’s no longer in her 20’s. While it’s not socially acceptable to discriminate against gays or blacks, somehow it has become okay to criticize women’s looks and choices as they get older. Not men, just women. “It’s still a sexist society.” She’s right.
