The problem is - these people clearly weren’t being ridiculed. They were smiling, they were participating, they were enjoying expressing their bigotry. I highly doubt that they’d be all that butthurt about their pictures turning up here. Unless, of course, they do that usual bigot thing where they try to backpedal defensively, whinging about how it could hurt their career, etc. Well, guess what? Too bad. Allow someone to take your photo with your own ignorant thoughts written on a sheet of paper (presumably by you) and that’s on you. The ridicule is built in to what they’ve done. They brought it on themselves. That simple. No pity.
