Sometimes my family surprises me. The other day, after seeing a trailer for an inane-looking movie called "Mama Mia!", in which a woman tries to figure out which of three hunks is her dad because she absolutely needs her father to "give her away" at her wedding, I remarked that I only want Dad to "give me away" at my wedding (assuming I ever get married) if my husband-to-be is walked down the aisle by his mother. Either he's escorted too, or I get to walk down the aisle by myself, like a big girl.
To my amazement, my mother and sister dismissed the idea, saying things along the lines of, "Oh, it doesn't mean that anymore!" (That is, "giving away" the bride no longer means the father is relinquishing dominion over her.)
I've heard a phrase along the lines of, "The greatest trick the Devil ever pulled was convincing the world he doesn't exist." The same thing can be said of sexism.
