No, no and no to all.
But we should offer them a better way. and that way is only possible through Christ. they need to experiance his love. and we need to shine. they need to see it through us.
Good.
Please apply the same reasoning to homosexuals.
Sodomy is a sin, same as adultery, assault, theft, drunkenness.
In many regards, even aside from pedophilia, it is more damaging to those who commit it and those against whom it is committed, than the others. It is a grosser perversion of human nature.
We won't be shining the love of Christ if we seem to give approval to homosexual behaviour.
There are no (that I know of) national movements to normalize, or develop acceptance of, adultery, drunkenness, violence, or theft.
Sodomy in general and sodomitic pedophilia in particular, are supported by well financed national and international organizations as objectively good things.
