I've seen it more times than you an imagine. Entitled kids with protective "it's somebody else's fault" parents. I've seen parents that had to bury their kids because of that attitude. Hence why my kids won't ever be that way.
I certainly agree with you there. I find it abhorrent that our country, at least parts of it, condone attacks on people due to a hat (or other items identifying political affiliation). It's part of the overall larger picture of a lack of politeness and civility that seems to be worldwide.
