There is only one group in today's society at whom it is still possible -- and acceptable-- to aim ridicule: On TV, men, especially Dads, are portrayed as incompetent morons who need women and children to protect them from their stupidity.
From the National Post: "It's deeply sexist, but what's even more troubling is that it's invisible as a form of sexism..."
Men are a convenient target. Generally we go quietly -- and competently -- about our daily lives and pay little attention the sexist garbage around us. The trouble with not speaking up is that if we do not counter these negative stereotypes, our boys -- and girls -- will grow up believing them.
