@beardyunixer @aral at least pawns are generic and can apply to anyone from any minority or majority group. "idiot" pretty hostile specifically towards people with disabilities: http://disabledfeminists.com/2009/10/11/ableist-word-profile-idiot/
@aral My only nit with this is that the people who are being useful idiots are, generally, not the people who see a problem and want to fix it, i.e. not the people who will be viewing your talk.
I'd go so far as to say we have pretty terrible lines of communication with the people who are the problem... and that's part of the problem.
