This is nothing more than testing the waters for the first time a church refuses to marry a gay couple.
Newest tactic with these people - if the voters don't do what they want, the government won't do what they want - sue em.
Sorry, this isn't a marriage issue, this is a school admittance issue. Can I be permitted to believe that the child is blameless for the act of her parent{s}? Why not educate this child, she's not responsible for the behavior of those she lives with.
