Hi, Sair,
I think you have made several unproveable assumptions here … let me point a few out…
Now, Sair, i am sure you know that hedonism has been tried over and over and yes, over again - and it really fails badly every time. The more who try the faster the decline of the civilization involved. We really are more than the sum of various lusts. And, yes, this is strictly Natural Law that is written in the hearts of all - not just ‘theistic believers’.
The annoying problem with this approach is that we are NOT 'blank slates, free of interstes and preferences…" Such an argument may make sense to someone trying to defend their lust for another - but, if there was someone sneaks up and removes your wallet or iPhone or lap top - one would expect to hear, “Hey! That’s mine! And, you can’t take my stuff!!” The ‘lifter’ (don’t want to disparage his personhood by calling him a 'theif;

) may say, 'Oh, no, Sir - you see morality is subjective - and, I just need your stuff. Thank you very much." How does this ‘subjectivity’ vs ‘objectivity’ argument of your stand now, Sair?
Actually, Sair, it is you who are making the unfound assumption here - that you can act as you will, sodomize whomever or whatever, and think you are immune from consequences. While sexually transmitted diseases are not limited to homosexuals - there are other (and actually much worse) conditions to consider. Prior to 1973, homosexuality was identified as a mental disorder - and one that can be both recognized and a course of treatment initiated. After 1973 the APA simply wrote it out of their category of diseases - like writing alcoholism, or schizophrenia out of existence is really going to do something - except ignore the problem.
Here is a quote you may be interested in: “In 1973, the American Psychiatric Association (APA) declared that homosexuality was not a disease simply by changing the 81-word definition of sexual deviance in its own reference manual. It was a change that attracted a lot of attention at the time, but the story of what led up to that change is one that we hear today, from reporter Alix Spiegel. Part one of Alix’s story details the activities of a closeted group of gay psychiatrists within the APA who met in secret and called themselves the GAYPA…and another, even more secret group of gay psychiatrists among the political echelons of the APA.” And, the link:

The age old problem of treating people as objects leaves profound scars on the psyche and one that ultimately destroys the person. it is more than ironic that Oscal Wilde wrote the “Picture of Dorian Grey” - but, it unfolds multiple truths on what path the real destruction of the psyche takes. There are no immediate lab tests for this - so, the casual view is that there are no consequences - but, just think about it: what in life is without consequences (either for good or evil)? Virtue is simply the habit of doing good, while vice is the habit of doing evil - they do not determine the acts - but the more you lean to one side or the other the more you are inclined to follow that course.
Just look around - there SIMPLY IS NOT GAY SOCIETY that has been in existence for any length of time. Yes there is a long and complex history of homosexuality throughout the world - but, they have ALWAYS been the minority - the abnormals amongst the normals. And the reason for this is that they can not shoulder the responsibilities of a real society. Like a paracite, they can only life off of the work of others who build a society - with the citizens of the next generation.
This is another half-baked idea that is presented as wonderous enlightenment - but, when fully examined it is found to be quite wanting. We are not talking about something like an art preference, like those who would argue abour Monet or Degas - it really isn’t a matter of taste… any more than your wallet, or iPhone or lap top are matter of discussion as I remove them from your property inventory sheet - to mine! This means that there really is objective morality - and one can honestly say that homosexuality is “objectively disordered”

This means that there is nothing you can do to make it ‘ordered’ just like there is nothing that can be done to make my taking your property, morally acceptable.
Those who argue that stealing your property is evil are not ‘morally superior’ - if you just think about it as you hold on to your property - you will just consider them to correct.
God bless
