The word [bitch] has been liberated for all society to use.
Words that are for the most part commonly used in disparaging contexts are never ever liberated.
The idea of a disenfranchised group of people taking back, reclaiming, "liberating" word(s) used to debase themselves and their communitites is, quite frankly, horseshit. Is there a mathematical equation showing the amount of useage over the amount of individuals using multiplied by the remaining years left it will take for the implied word to lose it's sting? That type of rationilization is ludicrous, and I'm surprised more people don't get called out on their horseshit rationalizations. This is nothing more than internalized, self-imposed racism, homophobia, and sexism taken to a preposterous level. If this type of rationilation, or, reasoning were to work, then words like "faggot," nigger," and "bitch," among others, can and should be used at one's leisure, but you can't because words like those will be forever tied to grave and deplorable injustices inflicted upon certain individuals and entire groups of people. And why should those words be "liberated" anyway? For the love of pete, why would anyone feel the need to pepper everyday conversation with those words? I don't get it, and never will get it.
Needless to say, I think phrases like, "you're acting like a woman," and various other like-minded phrases are also horseshit. You're kidding yourselves if you think this is a favorable and gracious response. It isn't. It's used to undermine and weaken the male spirit by implying that women are weaker than men. It's much easier to make allowances for poor behavior than it is to rectify it, particularly if it's ingrained, and that is exactly what this type of behaviors is. It's unfortunate that "you're acting like a woman" doesn't immediately conjure up visions of strength, power, and intelligence for the majority of men. Stop fooling yourselves and cut the crap.
