Insulting other people just for the hell of it like Charlie Hebdo doesn't display a sense of humour it shows pig ignorance and prejudice like the racist comedians of the 1970s.
Bigots always claim to have a sense of humour when insulting the weak and powerless. When it gets turned around they have none whatsoever.
People with a sense of humour can make you laugh without resorting to bigotry, and the best humour is self deprecating.
That's why British humour is renowned throughout the World whilst French Comedy is an oxymoron.
