The court cases will have a huge effect.
A significant turning point will be when people finally realise what Stonewall & Mermaids etc have been up to, perhaps if Stonewall Champions start being sued by detransitioners - then it'll be like rats deserting a sinking ship, no one will want to be associated with gender ideology. It'll be like Kids Company on steroids.
There will be a LOT of back-peddling among politicians.
Possibly there may be some scandals also, in the vein of Jess Bradley but more high profile. If so, that'll speed things up. As would a hard-hitting expose of what's been going on e.g. with the quackery of childhood transition.
There will probably be a few fall guys - my money would be on Mermaids and Gender GP as neither CEO comes across as terribly smart and I imagine they have implicated themselves all over the place, leaving them open both to being sued and also to taking the flack. I would imagine their friends in high places will drop them like a lead balloon once the shit hits the fan.
But however we get there, we will get there eventually. Gender ideology is a pack of cards, it has no substance, there is no evidence underpinning it, only indoctrination. And so, it will fall eventually.
It's not a matter or if, but when.
