That's one moral, for sure. But we have to account for the leering comment that "Carrie has a promising solo career." I think we understand what that means, and it strongly suggests that Ms. Prejean quite willingly placed herself into a rather unwholesome situation.
The other moral is that you should be mighty careful about allowing yourself to be lionized by Christians (as she also quite willingly did), when there's a better-than-even chance that your past will cause you to be lion-ized by the other side.
It’s one thing to masturbate, and quite another to tape it and keep the tape lying around.
One is more or less innocent. The other is reallllly stupid.
