No, I don't think it is wrong at all. I have absolutely no problem with them (or anyone) not going for any reason. I just think if I were in that position even if I was an Anthem kneeler or whatever the case is, I would still go just for the experience. If Trump wanted to do something smart he could have said, "Hey, maybe we can use this opportunity to talk" and had a conversation with the players about the injustice that exists and about ways to effectuate change. Instead, Trump acted like a crybaby and made a fool of himself to the whole country...except his base who for some reasons sees this as a positive.
