If you're a gay teenager with homophobic parents, and there's a real chance they'd throw you out on the street if they found out you were gay, you should probably lie to them about it. Even in college, if you're still financially dependent on them, I think it's okay to lie. The minute you're no longer financially dependent on them, you should absolutely come out for your sake and the sake of the world. But it's OK to lie if you need to to keep your education on-track.

In the ordinary course of events, parents are allowed to not support their children in college. So I'm puzzled as to what the principal at work here is meant to be. "It's ok to deprive people of their autonomy on the basis of a moral belief of theirs, even if this belief doesn't cause them to undertake any actions that would be considered immoral in the absence of the moral belief"?

Suppose I think that being a communist is immoral. Is it thereby ok for me to found a charity called "Workers Communism", solicit donations from communists, and then secretly donate them to the US Republican Party?
