Exactly. I feel free to call myself crazy as well (though I only do it facetiously - I think of myself as having a medical condition I was born with, and wouldn't ever use it, period, for someone who would matches the popular image). I don't even, personally, feel particularly insulted by someone else calling me that, regardless of their motivations.

But I wouldn't ever use it with someone that I didn't know felt the same way and also already knew I was bipolar, and never in public where I could potentially hurt someone else. Just because I don't feel hurt doesn't mean that it doesn't hurt them; and if I help further by minimizing it in popular usage, all the better.

I do slip and use it accidentally sometimes, though. I'm working on it.

It's the same reason I speak freely about my diagnoses to whomever. (Well, not to my bosses, for obvious reasons, though I wouldn't lie about it if they brought it up.) I'm not ashamed of it, and if I can help remove a little bit of the stigma, I might eventually be helping someone who does.
