A Mormon isn't going to physically molest you with his belief.
Of course! Just look at the population numbers as it pertains to sexual identity. That doesn't make your case. If the situation were reversed, and there were only between 2% - 5% heterosexuals in America, there would be far more homosexual assaults compared to hetero.
I come from Europe and I live in a country where the vice Kanzler (equivalent to your vice president) is a declared gay. That is, I might perceive the gay problem differently.
I also believe that if we want to make a point against the rampant secularization of our world, we need to use the same weapons of the lost: logic. And I am convinced that we can defend the Gospel using logical thinking.
I don't think that your post goes in that direction, unfortunately. If you think that homosexual men might molest young boys, then we should assume that heterosexual men teachers might molest young girls. The only consequent and safe solution would be to hire asexual teachers, which will be difficult.
Comparing homosexuality with pedophilia is dangerous and will not take us anywhere, in my opinion.
Jesus never had to. He just used scripture, to believer and unbeliever alike. This is the problem most "scientific","logical thinkers", have, they seem to try and squeeze faith into "logic". It can't be done, and scripture screams at us in the opposite when it comes to faith.
Should you not "perceive" homosexuality from a Christian, scriptural viewpoint, and not because you live is a decidedly secular country with a gay politician? The fact that he is gay, and the country embraces homosexuality, has nothing to do with what the scripture has to say?
And how are you going to witness to the lost, then? I have no idea where you live, and it is entirely possible that in your neighborhood it is possible to win the lost by using scriptures only. But I doubt you would be successful in your souls-winning endeavor where I live. Here atheists have a very high education, they are pretty well-off and, often, they know so much about the Bible as I do. Of course, I can sit down and say that they had it coming, but I don't think I can call myself an evangelical Christian if I am not able to bring to the Lord and save the most challenging cases. Bringing illiterate or defenseless people to the Lord is easy; try to win an academic European atheist if you can. I already brought two of them to the Lord, and my success was due to the deployment of reason and logic. And you can win them using reason, of course! It would be self-defeating to admit that our faith cannot be defended by reason and logic, wouldn't?
