Of course.
I think the question really turns on multiculturalism.
The school fascist said that it didnt have anything to do with sex ed so notification was not needed.
The father objected because a kindergarten child was being exposed to two texts one featuring a lesbian "family" the other a "gay" family.
As far as the father is concerned he was right in objecting, he could have handled this differently but the entire case just shows how far the multiculturalists are going to go making sure that every kid is indoctrinated with this crap.
