Because this shit is linked to human rights in the West and the West only. This emboldens AGPs and they can call people who laugh "bigots" and "nazis". Any AGPs outside the West must keep their fetish secret, or they can expect heaps of ridicule with zero sympathy.
I second this; Bailey et al also touch on this. The environment of the “West” previously has become a lot more accepting, a gradual change with the decline of prudishness tied to the loss of face for unseemly or deemed degenerate behaviour.
1) Young effeminate homosexuals were usually already social pariahs, given that their behaviour is so innate that people can only take notice before they are old enough to properly learn what concealment and lying is. You could argue that in a very hostile strictly gendered society, they have nothing to lose with a transition, which even may offer some concealment or plausible degrees of deniability to others. I would hazard a guess that this is why you see so many black American Transgender individuals that are being murdered: on average the Black American demographic seem to be very conservative in their views on sexuality and behaviour.
I have to say that I found the depiction of male brothels in The Alienist do an excellent job in showing how deviancy (from the norm) throughout history has been known, willingly ignored and permitted as long a certain set of rules was obliged by all parties, especially if the privilege of power and money was involved in skirting boundaries.
2) Like AGP’s, as heterosexuals or bisexuals, have their awakening when their puberty starts in their preteens initiating the male sex drive. Back in the day they would have the wherewithal to conceal their behaviour and satisfy their needs behind closed doors. The social environment has shifted now into a more receptive or at least understanding manner so that they may even gain something from openly flaunting it.
Or you are like a Pritzker, Rothblatt, Levine or de Sutter already in a position of money and power so that you may not have to worry about becoming an outcast these days.
@Positron is hits it on the head that the current Western Zeitgeist celebrates it for various reasons. Money ensures that the less palatable sides of this demographic are kept out of sight. They still know how precarious their position is as they try to conflate the two by claiming HSTS traits, e.g. displaying gender atypical behaviour early on; they lie about it.
Say what you will about the Middle East and Japan, but their rigid more collective based culture seems to ensure that these men (still) have too much to lose by being as openly brazen as the currently typical white AGP autist is within their society. For now I have no reason to believe that is not as equally prevalent among men in other places of the world as white WEIRD's
EDIT: meant the WEIRD acronym, typos
