My children go to a private Christian school, and they will not have friends that have gay parents.
I teach my children to show respect for all people, but they do not have to accept it or tolerate it being shoved down their throats.
Every parent has the right to raise their children how they choose, send them to whatever school they choose, and allow them to be friends with whomever they choose.
It's our choice that our children do not associate with queers or queer families. I respect your choice/your opinions, it's your decision.
