I think if you go down this road then you might as well say that the bigotry and bullying, both learnt activities, are more acceptable than behaviour that is genetically determined.
Understood. Perhaps one of us just has less faith in the way human beings sometimes like to conduct themselves.
This idea is closer to the discussion/debate had between those who live in "deaf culture" and those who do not. Deaf people, within the culture, feel that it would be extremely evil to invent a procedure through deafness would be eliminated in or world, insisting rather that people need to put energy into finding ways to better align the deaf with the hearing world. They do not see deafness as a handicap.
In both cases, I think the cognitive identities of the currently existing are being projected onto the potential identitites of nonliving/nonexisting future entities. Yes, we must struggle to make life comfortable for the existing homosexuals/deaf, but it is unlikely that the world is ever going to be as safe or well designed for them as it is for the majority. The world is designed by the majority, though sometimes accomidations are made. However, living a life of exception and accomidation is not the same as living a life free of having to worry about whether the next town you're in is going to be as accomidating to your inalienable condition.
In other words, I believe that what you would like to see is an ideal that can only exist at the intellectual stage. I don't really believe that the entire world can be made as fair, safe, and efficient for homosexuals as it is innately for heterosexuals (or the deaf). The real problem is that people are being hurt, killed, and tormented. We know why, but no ammount of outreach and education is going to remove it entirely. If a medical procedure existed that could remove my child from the real problem, I would take it.
In this way, I think I am less about ideals and more about physical realities than some. I respect and appreciate the need for ideals, but when the physical reality being discussed is the potential pain and torment of future beings, I've got to go with the most efficient way to eliminate the risk, whether they are the most idealistic or not.
I very much understand your position, though.
