Since you've mentioned age (and I've seen another thread with a quote saying LGBA and T**Fs are old) I will say something I've observed.
The LGBA events and the conference- mostly middle-aged people, right? There was a photo on Twitter where one user commented "would be quicker to do a hair count than a head count".
Marion Millar and the people who turned up to support her in Glasgow- all mostly middle-aged people, right?
Graham Glinehan- in his mid-50s I believe.
Now think back to that LGBT event were someone wearing LGBA attire was not welcome. The crowd chanting "trans lives matter" at him so he would leave were all young people.
The students who protested against Kathleen Stock's employment. Young.
Think of pretty much anything Stonewall and there will be a mix of age-range including large numbers of young people (as opposed to dominantly old people).
The point I'm getting at is times are changing. The attitudes that were acceptable 50 years ago just aren't accepted by today's younger generation.
