It's impossible to know how one would react in a real situation, but as I sit here thinking about what if I saw one of my sons in that photo, first I'd be heading to the hospital to check on his condition, and I'd seek to find out if the story held up, and then I'd be seeking out the person who posted it and offer a handshake as I apologized for the impossible language my son had been using. My son might not like the protesters any better, as a consequence of the injury, but he sure would get a refresher course from me that language like that isn't ever called for, and that hatred has a way of turning itself back on a person, sometimes out of proportion. Maybe the missing tooth will be reminder for the rest of his life to do better. Like I say, though, impossible to know. More important than my reaction, though, is that it's not likely the "brat" has much in the way of guidance. That doesn't change that his opinion of the protesters isn't of much value either way. Sometimes you just omit the disrespect, out of self-interest.
