Yeah,good point.
As for organizing .. once marriage was obtained, the gay orgs had basically nothing to do, so the tranny stuff became their new moneymakers. People here often see everything as one huge conspiracy, and I’m sure China secretly funds some of this stuff just as we fund stuff in other countries, but I think most of this is just “regular” liberals finding the next cause.
A lot of regular gays disagree with this stuff, just as a lot of city women disagree with trans in bathrooms etc, but only a tiny fraction speak out. The trans movement is literally the Emperor Has No Clothes.
In addition to your points, there is reason to believe that the trans movement is spurred along by gobs of money from one of the immensely wealthy Pritzker family heirs who is a trans type. In essence, he funded various organizations and doctors to promote trans ideology as medically valid. This in turn led to key opinion makers, the news media, and courts to endorse the trans ideology. I suspect that when the money runs out, the pushback will become more effective.
