Are these the same "professionals" who desisted homosexuality from the DSM in the early 70'S? Are these the same "professionals" who believed treatment and rehabilitation was possible for offenders? Modern psychology is even more politicized than climate "science".
But I take his point. It begs the question of the nature of homosexuality. So many things arouse a man, but at bottom is the way the twig is bent and what opportunities are available.
