I was just wandering around the edge of the Twitter cesspool on this.
It seems that this is an "agreed" tactic. When someone calls you a racist, you call them a paedo. I won't link it because it'll only add to his impressions or whatever but he's whining that being labelled a racist has serious consequences and several of his supporters have waded in, their responses suggesting that this is a discussed and adopted tactic. They see it as tit-for-tat which, of course, it isn't.
Now, he has massively fucked up this time. There is a Simon Blake who was convicted of various offenses - I didn't go into details as to what. But the Simon Blake he has accused is the deputy chair of Stonewall. OOPS.
