The American comedian, Andrew Schulz performs in front of audiences who are completely mixed in every sense, they are properly represented and diverse. Schulz solves the diversity problem in a rather interesting way, not by pretending that touchy subjects like race or gender don't exist but by highlighting the distinctions and taking the "mickey" out of them. Perhaps from a creative point of view this is a better way to incorporate the diversity with humour rather than being politically correct and skipping around the topics. Do you pretend to make people not notice ethnic differences? Are you anxious in the presence of any of those differences, or do you acknowledge them and make light of them?
