It’s really easy to go “my apologies” and then address them properly. it’s only an issue when people make a scene out of it and go out of their way to insult them further.
That's not a case of accidentally misgendering someone. That's someone displaying a pattern of abusive behaviour against a group of people.
That's a load of ********. He was arrested not for misgendering someone but for repeatedly turning up to a school he had been sacked from, in breach of a restraining order. Do better, and don't take twitter **** at face value.
What did he get the sack for mate, do you know? Must have been fairly significant if they had to get a restraining order... why on earth would you keep turning up???
He apparently harassed the headteacher over the school's policy on transgenderism. A disciplinary process was started and he was suspended whilst it was ongoing. He then carried on turning up despite being suspended and refusing to leave so the school had to get an order. He then still carried on being an arse so got arrested.
