If they'd brains, they'd know that it's impossible for a human being to change sex, so any ideology or campaign based on the opposite of that fact is fatally flawed.
I think the loudness, the aggression, the #nodebate, the vilifying, the violence, the fog of confusion, the 'it's all too confusing', the nasty condescending sarcasm [see the Sunderland Minster thread], the threats of litigation, the 'toxic culture war', the name-caling, the personal attacks etc etc are there to try to cover the factual void at the centre of transgenderism.
It's 'bluster and shout and threaten your way out of having to engage your brain and defend your claims in a reasonable way', isn't it?
