I often hear that people should treat slurs as badges of pride, like "bastard" in Game of Thrones. Is that strategy ever successful? Can you name any group in history that managed to reclaim a slur? I can't, so that seems like a losing strategy. The winning strategy is to come up with a better sounding name for the group, and then marginalize anyone who keeps using the slur.

I think "queer" has been claimed. I haven't heard it used offensively in a long time. [EDIT: I'm not in that group, so perhaps my impressions are skewed, but twenty years ago I heard it all the time.]

Yeah, my jew friends call each other kikes and own it. They're all millionaires now.

It seems indicative of hostility and disdain- an unsubstantiated dismissal.

And regardless of how you see it, plenty of people associate it with being mercilessly bullied.
