Seriously, were you home schooled? Do you no longer remember the social structure of schools? When word would have got out that her parents would be lesbians that is exactly going to be known for. It will be mentioned often during her tenure of a school student. THERE IS NO GOOD THAT CAN COME OUT OF HER STAYING THERE. NONE. Not for the child, and not for the school.
There is a boy in my son's school with lesbian parents. He doesn't get teased. And another on another son's soccer team. The kids even care (and they are 14, so they understand.)
