I'm not going to improve on the many excellent points made by other posters, but I'd like to pick up on some revealing things that AidaP said about Pride:
.. that's at the core is what's it about - accepting and loving people of all makes, besides haters.
Shocking stat: most people at any major pride are not actually part of LGBTQ, just supporters.
So there you have it: Pride is not about lesbians and gays anymore, and according to AidaP, it's not even about LGBTQ people anymore, it's about 'people of all makes', and most of the people who turn up at it aren't LGBTQ at all.
So Pride is about absolutely everybody except haters. And possibly The Wrong Kind of Lesbians.
It sounds like a great big amorphous anything, really. No wonder it's losing support and sponsorship.
That also was part of pride since the very beginning at stonewall.
Do you mean Stonewall the organisation or Stonewall the bar and riot?
Two very different things! We know from contemporaneous reports what happened at the Stonewall riots, and attempts to retrospectively trans it have fallen flat, so I'm assuming you mean Stonewall the organisation.
