It probably isn't understandable to those who effect prejudice and bigotry of "short eyes". But to most people the fact that the OP has chosen to title his thread ”Biological origin of homosexuality” the plain and reasonable understanding would be the biological origins of deviant sexual proclivities and not deviant sexual behavior. Maybe that isn't understandable to you?

What causes you to make the illogical and irrational leap from a discourse of the biological origins of mutations for deviant sexual orientation to the irrelevant present state of the evolving paradigm that is the social construct of “legal consent”. Why are you attempting to separate the biological imperative of humans to engage in sexual activity with other humans based solely on some arbitrary time frame? Why do you feel the need to differentiate and discriminate based on some exceedingly fluid parameter?

Its been put forward mentioned many times within discussions on the topics of sexual orientation, that it is often the case that the loudest voices against a particular orientation are eventually revealed as closeted practitioners of the very orientation they've railed against. Vociferous anti-homosexual voices have been revealed as closeted homosexuals, it seems likely that those who so often seek to demonize pedophilia would include closeted pedophiles among their hateful throng.



To respond to the off topic question about alleged differences between homosexuality and pedophilia.

It was only a few short decades ago that homosexuality was categorized as as a mental defect, the apparatus of state was employed to by any means correct such defect, homosexual behavior was criminalized, and homosexuality was a societal taboo.

Today pedophilia except in the most enlightened societies (Sweden and Islam), is considered as incorrigibly deviant as homosexuality was before we achieved our present state of enlightened tolerance. Pedophilia is only a crime because the society has yet to recognize and accept the full panoply of human rights for all humans regardless of the their chronological age.

The intolerant among us wallow in self righteousness as they deny the full human right of self determination to individuals who through no fault of their own have not yet existed the unjustly imposed requisite time period.
It seems that certain people are perfectly willing to deny fundamental human rights to large segments of the population based on nothing more than how long they have existed and certain people are perfectly willing to persecute those who are born with an orientation that is at odds with the discrimination those same certain people fail to object to.



Pedophiles are criminals only because certain people deny people under a certain age the human right to pursue happiness with people who are predisposed to be attracted to them. It's hate and bigotry imposed by a majority on a disenfranchised minority and those that seek to love with them.
If hateful and bigoted hearts could be opened and society could advance to appreciate the true beauty of all love between all humans then the stigma of sexual age-ism would cease to exist and everyone could live there life with the liberty to pursue their happiness.
