Actually they think (mistakenly) that such a waiver/admission will protect them from litigation (well, that is probably true in the 9th Circuit) for any suit brought from a parent claiming harm to their children at the hands of an “admitted” homosexual.
All-in-all, I would that parents litigate for “propagation of indecency with a minor” for even discussing their so-called lifestyle with their charges.
That said, the BSA will crumble to dust with in the quintennium.
They are not going to treat homosexuals like criminals on probation. They are more likely to treat Christians like that.
