Curiously, the same folks who throw that around are quite offended, justifiably, when a man breaks out "fat bitch" to try to destroy the humanity and dignity of a woman.
BTW, I have no time for angry young men who blame women for their problems. However, most of the people who have this slur attached to them aren't angry at the opposite sex. Mosat are depressed young people, male and female, who for various reasons, are isolated and lonely. They're just desperate for connections with other human beings. If you've ever personally listened to a young adult express despair in situations like this, it's gut-wrenching. Often, it's because they lost life's lottery in the looks department. This is particularly true with young women. Life's hard enough just dealing with the things you can control.
