I very, very much doubt that Danny Baker’s tweet had any racist intent at all (but then until it was mentioned on their wedding day I had no idea she was mixed-race, I still can’t see it myself.) That seems like a huge overreaction but that’s the danger with Twitter, there’s no room for nuance or explanation.
The second incident is the more worrying one by far and a curious target. Was it the Jewishness or the Brexit stance that prompted the perpetrator’s single neuron to melt?
