Ok, I'll bite. Is actually already been done.
A core statement of your thesis: "Increased tolerance for homosexuality will result in more minor male children (AKA, "boys") being raped by homosexual male men."
Which is simply not the case. Period, full stop.
We do have more victims coming forward, but many of them are also coming forward as adults, and referring to assaults that happened when they were children (things such as the Catholic church's issue).
We are more likely to hear about the crime soon enough to actually prosecute today, but it's not happening at an increased rate.
>Even if we believe the absurd notion that male homosexuality and the rape of boys is wholly unrelated, the incidence of boys being raped by practicing homosexual men would likewise be reduced, given that only some small percentage, X, of practicing male homosexuals engage in pederasty. Are twice as many men, in this more tolerant America, willing to engage in homosexuality than in earlier years? Make that roughly 2X the number of raped boys.<
Unfortunately for your thesis, it isn't a straight-forward correlation. Things in life rarely are.
What you suggest, that with twice as many men willing to engage in homosexual behavior=twice as many boys being sexually abused doesn't take into account the issue of the person being a pederast. You're too hung up on their sexual orientation.
Such deviants are, generally speaking, VERY willing to take the risk of offending, and have been for years. Simply doubling the number of men willing to act on homosexual urges has no effect on the number of men willing to act on pederast urges, as the two don't correlate.
Or, to put it easier: every "boy lover" pederast is homosexual, but not every homosexual is a pederast...
