Thanks - I think the trend you describe is indicative of a deeper motivation that I imagine is suspected by most on this forum: what these people are looking for is not medical relief, but societal affirmation of the (supposed) normality of their disorders.
If you want somebody to whack your tallywhacker, and you’re willing to pay, you won’t have any trouble finding a professional willing to take your money. Ditto if you have a perfectly-functional right arm, but you feel like you want to go through life as an amputee. But deep-down inside (for some, right near the surface), lots of these folks know they’re messed up, and what they most desire is for society to affirm their fantasies.
And I’d still contend that something similar was the main driving force behind the travesty known as the same-sex “marriage” drive.
I agree with your analysis.
