What has the kid to do with it? It’s the parents not the child.
If they kept the child in the school, how long do you think it would be before the two lesbians sued the school for teaching the daughter that their lifestyle was sinful and causing them emotional distress, or for preventing them from attending a school function as a couple, or some other event that insulted and offended them?
The school is wise to resolve the situation now - any lawsuit filed will be tossed immediately, especially since the school's handbook, which they lesbians had to sign, specifically stated that the school had the right to refuse to enroll any student or discontinue the enrollment of any student for whom the "atmosphere or conduct within a particular home is counter to or in opposition to the biblical lifestyle that the school teaches", specifically including homosexuality or an "alternative lifestyle."
