OK, so this is very mean-spirited of me, but I've just had a delightful exchange with someone on Twitter.
The subject was #shameonscotland which is currently trending. Someone said that the bill, and the people opposing it, were transphobes. And they questioned whether the terfs actually believe that predators pretend to be trans.
So I sent a couple of links to news reports of predators who had claimed to be trans in order to get access to women, and assault them.
Yeah, my interlocutor declared, but that was a transwoman assaulting the ciswoman, not a predator pretending to be trans.
Reader, they took that tweet down almost instantly. Maybe because it didn't make the "ah-ha!" point they thought it did....
