Also, another thing:

Something that nobody seems to have considered here, neither you nor BK nor anyone else who has Entered the Fray, to use Dissident's preferred expression, is that by saying that, he looks overcompensating. True, today it's not yet very common in public to hear that overcompensation in pedophobia is the reflection of hidden, probably self-hated, pedophilia. We hear that very often regarding homophobia, and also often enough about racism. However, although it's not yet common regarding pedophobia, the mechanism is understood by everyone. By saying he'd kill the guy, he is overcompensating, and therefore actually outing himself more than if he had chosen a less confrontational reaction. Of course, the original anti is the perfect example of "doth protest too much" - I'd investigate what he's got in the closet. Seriously. That kind of overcompensation just isn't right.
