Boggles the mind

I got into an argument about insults with someone today. I was basically told that it's bad for a man to call a woman a slut but it's okay for a woman to call a man a dick and that white people's insults toward black people can be conceived as racist but black people insulting white people can't ever be seen as racist. The wrongness of insults (because it is wrong to call people names no matter the race/gender/sexual orientation/religion/etc.) aside this is insane. So basically, the behavior of one group of people is always more excusable than the other's? What the...! Talk about equality. Sheesh.
