He’s perhaps not the smartest with his use of social media, he’s quite clearly targeted by people winding him up and he bites a lot of the time. He seems part of this toxic side of social media whereby people involved in the toxic behaviour always blame other people whilst continuously reacting to it rather than reporting or blocking the individuals.
That said, the tweets people are quoting are over 3 years old, they’re not great at all, but I’m not a fan of digging up things people posted on social media years ago. He does a lot of good work for a lot of good causes (not least his comments this evening) and whilst that is no excuse for racism, it does make me inclined to believe that the comments were misplaced rather than illustrative of him holding racist beliefs.
