Our increasingly permissive culture is not equally permissive in all directions. You are ignoring certain clear trends.
For one thing, it has become increasingly more 'shameful' for a man to date a woman much younger than him. For another, our culture has increasingly pedestalized children; the idea that we are now going to do an aboutface and legalize child rape seems a huge stretch.
I also have to ask, if more females are abused as children, and being abused as a child directly leads to homosexuality and pedophilia, why are there more male pedophiles than female? Doesn't that one statistic blow the rest out of the water? (I'm not stating that there are no female pedophiles, just that more are male.)
Also, I have to wonder if so many different species of animals were sexually abused in prepubescence as to make them often display homosexual behaviors.
Homosexual behaviour has been observed in 1,500 animal species.
"We're talking about everything from mammals to crabs and worms. The actual number is of course much higher. Among some animals homosexual behaviour is rare, some having sex with the same gender only a part of their life, while other animals, such as the dwarf chimpanzee, homosexuality is practiced throughout their lives."
Animals that live a completely homosexual life can also be found. This occurs especially among birds that will pair with one partner for life, which is the case with geese and ducks. Four to five percent of the couples are homosexual. Single females will lay eggs in a homosexual pair's nest. It has been observed that the homosexual couple are often better at raising the young than heterosexual couples.
When you see a colony of black-headed gulls, you can be sure that almost every tenth pair is lesbian. The females have no problems with being impregnated, although, according to Petter Boeckman they cannot be defined as bisexual.
"If a female has sex with a male one time, but thousands of times with another female, is she bisexual or homosexual? This is the same way to have children is not unknown among homosexual people."
But nothing like this could ever be natural of course, or even mostly natural. Sure, abuse plays a part for some, just like if you are physically abused or live with alcoholism or a smoker, chances are higher that you'll display the same behaviors than those who weren't...but it's not an absolute.
Those are interesting articles, but they're basically just guessing as much as the studies they denounce. They're not proof or fact. Studying a couple thousand homosexuals and pedophiles does not prove anything even close to concrete.
