"Why do you think that there's more predators in the Catholic Church than in the general population?"
I don't. I'm undecided. I'd need to no more before I make up my mind. Otherwise I'd just be guessing.
But seeing as you've already made up your mind, I'm asking you to share your reasons for thinking the percentages are roughly the same.
"sexual predators make up a small portion of the population and therefore would likely make up a minuscule portion of both populations."
You're assuming your own conclusion. The percentage in the population gives one no information at all about the percentage in a subset of that population.
"The Bible contains six admonishments to homosexuals and 362 admonishments to heterosexuals.
That doesn't mean that God doesn't love heterosexuals. It's just that they need more supervision."
