You can't have it both ways. Im totally on board with the idea that we do not get to chose to whom, or what the object(s) of our sexual desire is.
The largest sex organ is the brain, a very complex organ in a very complex organis, the human body, and neither is immune from errors. The brain is hardwired for humans to seek other humans as mates, and more specifically for men to like women, and women to like men. The human body is designed to come in two basic forms, male and female. Sometimes folks are born with parts of both sets of sexual organs, and sometimes the brain developes improperly.
Occasionally something goes wrong with the body or the brain; these errors can manifest as mental retardation, birth defects (gimpy arms and the like), hermaphordites, and sexual deviance.
The vast majority of the time people are born "normal" with a pair of arms and legs and a properly functioning brain, no retardation, and sexually healthy. Sometimes folks are born asexual, with no desire for sex whatsoever. Sometimes an individual is
born and developes sexual desire for inanimate objects, I saw a program on tv where a dude got his rocks off by making love to his car. Sometimes people develop attraction towards animals and they buy velcro gloves.
Then there are the kiddie lovers, which buck, by the way is not just a manifestation of a desire for control/power. These people are genuinely attracted sexually towards children. Sure, some have a desire to dominance, just like some heterosexual, otherwise normal people do. Those folks rape grown women/men instead of little kids. The pedos may also express a sex preference, with some only attracted to same sex (which is far more common) and others attracted to opposite sex children. They often talk about how children are sexual beings, and can seduce you, and they imagine loving relationships. Also, the fact that most male pedos do not penetrate their "lovers" is more evidence that it isn't about control/dominance. That is their natural (to them) target for the love they have to give.
Then there are the most accepted group of sexual devientes, the homosexuals. Something in their brain makes them focus their romantic interest towards those of their own sex.
I'm glad you pointed out eye color and hand dominance. Both have a basis in physiology. Right handed folks have a dominant left hemisphere of their brain, and naturally lefties (the good kind) are right brain dominant, thus there is a physical cause for your exhibit a. As far as eye color, there is a genetic cause for that as well, so exhibit b of yours also is an argument in favor of what imsaying.
In fact, several researches have noted physician differences in the size in certain structures within the brain of known homosexuals compared to their sexually normal fellow humans.
Researches have also noted that there tends to be a genetic cause; homosexuality tends to be a trait folks inherit through their mothers contribution to their genome.
Now, consider this... Dr Judith Reisman , president for the institute for media education conducted a bunch of surveys with the grant she got from the justice department (in order to get a grant for research such as this, your methods have to be pre-approved by the body which governs such studies, with very strict criteria) found out some interesting data. One interesting tid-bit she discovered was that same sex molestation of young boys occurs at 5 times more frequency than the molestation of young girls by men.
Here is where the ability to even debate this arises. These numbers came from measuring the molestor, not the molestee. In other words, since there are far more straight-pedos than gay-pedos, the number of girls molested is higher. The "five times the rate" figure can also be said like this. A gay man is 5 times more likely to sexually abuse a child than a straight man is. These are department of justice statistics.
While looking for this info, you will find a lot of stuff saying this is bullshit. There will be rainbows on the page, and they won't provide much in the way of numbers/facts. Consider the source; department of justice, or someone with a pro gay agenda.
Having said all this, most, the vast majority, of homosexuals would never touch a child, and would find the idea just as abhorrent as you or I. But facts are facts, and it's foolish to ignore them.
There is something physically different going on in the brains of gay people, it can be traced though the female line of a family. Having said that, i believe that There is nothing wrong with being gay and the existence of a relationship between two consenting adults, regardless of the sexual makeup of the couple. I'm actually a proponent of marriage equality.
You have won the argument that your sexuality is not a choice, but you cannot win the argument that there is not a physical explanation for your sexual preference. As a deviant sexual orientation, it shares causes with others. No way around it.
I am not morally equating homosexuality to pedophilia, no rational human would. Although I will say the more rights homosexuals win, the more likely it is that pedophiles will push for similar rights, but that is no reason to deny the rights to homosexuals.
Just because the two may be physically similar/linked, in no way makes them similar in practice.
You got anymore circular arguments?
