Exactly. He's putting his 7 year old kid on the front line of HIS battle with the school district, exposing him to the negative fallout.
Incredible.
Well, this would appear to be easy for you to say given the benefit of 20 20 hindsight ..... but you don't honestly believe that Mr. Parker really would have sent his son to school as a pawn in his battle - and that he (by some strange powers that perhaps only you are able to define) was able to know in advance that his son would be be beaten up by a crowd of kids in his grade one class, but sent him anyway, do you? Are you suggesting that Parker used his son in some way as part of his own political statement and agenda?
Where do you draw the line with this? When I was a kid, my daddy used to go to my public school all the time to discuss all kinds of worldly and ungodly things that were going on and that he was dead against. None of this made me very popular in school, I can tell you that. Does that mean that my daddy shouldn't have dared go to the school on the off chance that his son would reap some negative consequences? If this is your view, then I would offer an observation that I don't think you believe there is very much that is worth standing up for.
