According to the Talmud, loshon hara kills three people: the one who speaks it, the one who hears it, and the one about whom it is told. 'Kill' may strike the modern reader as a bit hyperbolic, but when you think of all the friendships lost, careers stunted, and opportunities thwarted as a result of gossip among women, violent language seems appropriate. We cause serious collateral damage to the advancement of our sex each time we perpetuate the stereotype that women can't get along.
