I'm a little confused. Are you including people who are being harassed in "the crazies?"
People who claim - and in some sense believe - they've been harrassed when they haven't really, and people who grotesquely exaggerate minor incidents, could count as crazy in my book. I guess people who claim that all such claims should be believed, no matter how seemingly improbable, and race/gender groups condemned on that basis, could also be considered crazy. I tend to think they are mostly just bad, not mad, though the more radical ones may be somewhat disturbed.
