So she's saying that if David Walliams had a character based on a middle class white woman, who was an online bully, used poverty cos play, jumped from bandwagon to bandwagon (I'm vegan, BLM I'm cutting my black brother's hair, I had to change my name after racial profiling, I'm transitioning to non binary, I'm an alcoholic, I'm immunocompromised, I'm disabled, people are stifling my sexy garlic, #MeToo) then it would be offensive.
Hmmmmmmm, that WOULD prove a point Jack, just maybe not the one you wanted.
You are the offensive character Jack, if you wanna make the world a better place, take a look at yourself and then make that change.
