We used to have campaigns for equal rights for LGB people. This got traction because everybody except the most virulent homophobes could see they had common interests and giving them equal rights wasn't going to cause problems for society as a whole.
The most brilliant wheeze of the T activists was persuading the LGB activists to take them in, rapidly followed by the Q and all the other letters. I'm straight so maybe I'm missing something, but I can't see for the life of me what T and Q have in common with LGB. From where I'm standing, Stonewall seems to have decided that all the money and publicity was in the T area, not the boring old LGB area they were founded to work for, so in comes T and like a cuckoo in the nest soon comes to dominate the entire work programme of registered charity Stonewall. Baffling.
So now we have people with assorted unusual and in some cases clearly harmful personality traits claiming to be oppressed, asking Stonewall et al to lobby for them, expecting the police to investigate anyone hostile to their position as perpetrators of hate crime, amending the school curriculum etc etc.
It's a mystery to me how they've got away with it.
