Once again, it goes back to the obvious, but definitely un-researched, fact that homosexuals are far more likely to have both physical and psychological abnormalities unrelated, but possibly associated, with their sexuality, than heterosexuals.
In other words, their abnormalities are not *caused* by their homosexuality, but are independent of it, unless they assume or choose to intertwine the two.
Ironically, this leaves a lot of homosexuals walking around with treatable physical and mental conditions, because the assumption is that they are either part of their homosexuality, or as a consequence of their homosexuality.
The reason that it is un-researched is probably based in fear that if homosexuals are discovered to have a far higher percentage of abnormalities in their bodies and minds, that it will somehow be used as an excuse to despise them further.
But as it is, it just results in a lot of untreated suffering on their part, yet again ironically, suffering that would not be alleviated even if they accomplished their agenda.
As far as society as a whole is concerned, however, until these individuals who especially have psychological problems are treated for those problems, they are, and should be scrutinized, as much as anyone else with untreated psychological problems. It is not because they are homosexual, it is because they have some degree of untreated mental illness.
It's kind of like illegal aliens are criminals because they are ILLEGAL aliens.
We know homosexuals have some mental illness simply because they are homosexual. Homosexuality IS a mental illness.
I don't know what you are implying by "physical," but as for psychological pathologies, they has been extensively researched and validated. Homosexuals have elevated rates of depression, character disorder, substance abuse and suicide, and these have not gone down as "gay lifestyle" acceptance has spread.
Whoever told you such variables were "definitely un-researched" was "definitely" blowing smoke up your butt.
