Some people consider lots of things to be wrong, many of which people on this site participate in. I don't think it's enough that someone "considers" something to be wrong for them to speak in such a hurtful, sweeping manner. Of course we would all condemn a pedophile, but there's a lot of slippery slope between here and there and I don't think infidelity and pedophilia are equivalent. I think people should be very sure that whatever activity they are planning to condemn falls into the pedophile category before they use the most inflamatory and intemperate language they can muster.
Respect is a good place to start, and maybe people should ask themselves whether it's really necessary to depart from that in order to make a point.
