It isn’t the kids’ fault their “parents” are lesbians. Why punish them? Accept them. And then teach them the truth, that God’s word condemns homosexual behavior.
As long as they also boot out kids whose parents are cheating on their spouse or if divorced/widowed are fornicating outside of marriage, there’s no problem.
People should stop using kids as a tool to get their way. The kids are in this situation not because of the school, which is private, but because of the lesbians. Are they from another planet? Jeez, they pick a “Catholic” school? What would be the point? They don’t understand the Catholics view on homosexuality? No other private schools in the area?
It is a private religious school, I think it is disrespectful for the lesbians to assume that rules don’t apply to them!
For reasons that are completely outside the Church's control -- and are entirely within the control of those lesbian parents -- keeping kids like these out of a Catholic school is necessary for the school to protect other kids who might otherwise be influenced by this bizarre "family" arrangement.
