For reclaimed words, they've given (tacit) permission to the rest of the population to use it. For words that, like "Dyke," "Fag," and the N-word, it is not acceptable for people outside the target group to use them, because of the history, lack of permission, and that they are inherently different coming from a person in the majority group, it is not okay for a member of the majority/oppressing group to use them. Crazy has been reclaimed, to a degree. I call myself crazy. But other people call me crazy to oppress me, so it's not okay for you to use it.

And in this case, it's still being used as a weapon.

Seriously, this is *ism 101, why am I explaining it on UFF? The FW community should be past this. It's been rehashed over and over.
