It is not reasonable at all, but it is what currently is the reality. The current school system is brokena nd unreasonable. And it wasn't chosen by the father, it was chosen by the school system. If many parents will indeed be angry, then they should, and they should be at the school system. Being angry at the father is just the short-sighted and ignorant "let's go for the closest target" knee-jerk reaction.
