Reading the AMA guidelines, I get the impression that they dont recommend this therapy, not because it doesnt work (they dont take a position in fact), but rather because studies by other groups, including the APA have shown it can cause other serious problems.
Either way, the Torah is quite clear where it stands about people engaging in this specific “lifestyle” (this is a family friendly forum). To hold a parade that celebrates, promotes and flaunts this lifestyle, in the shadow of the har habayis, is worthy of condemnation in the strongest possible terms. The parade organizers made it abundantly clear how they feel about the sensitivities of other people when they refused to remove rainbow flags hanging in front of shuls such as Heichal Shlomo, no reason to tiptoe around them and their feelings and sensitivities either.
