So, after gay marriage became a thing, Stonewall's main fund raising war cry ended.

Their employees are people with jobs and mortgages to pay. This could put them out of work.

Hence the swap over to trans activism.

This is something of a problem, since transexuals back in about 2000 were only about 1/2000 people. Not a massive pool of supporters or people in need of help.

However this number expands miraculously if you start including adult onset AGPs and transvestites, and insist that all gender non conforming people come under the trans umbrella ☔.

Enter some trans billionaires willing to pump cash into this via astroturfing activism, and here we are.

Basically... The activists are getting loopier because most of the major issues have been remedied, so now they are taking on some very fringe issues in an attempt to stay relevant and keep the money coming in.
