I don’t find David Walliams / Little Britain funny, just not my thing, but I understand that we’re supposed to be laughing at the ridiculous characters and not with them - they are the objects of comedy with their ignorance and bigotry
Of course this can be hard for some people to understand, such as children (and those who share the characters’ beliefs). If I was concerned that my child was misunderstanding the books, I would talk to them about it - “that guy who laughs at poor people is silly, right?”
You know, have a discussion rather than tearing the author apart on Twitter. If SB has read all DW’s books he clearly enjoys them, and outright sending the message that his (SB’s) opinion is wrong isn’t the way to go
