I'm getting highly irritated about the leap to take offence these days. There is a whole apology culture that leaps on ANY mention of race, religion or whatever.
Let's look at the dictionary definition of racism:
rac⋅ism [rey-siz-uhm] Show IPA
–noun
1. a belief or doctrine that inherent differences among the various human races determine cultural or individual achievement, usually involving the idea that one's own race is superior and has the right to rule others.
2. a policy, system of government, etc., based upon or fostering such a doctrine; discrimination.
3. hatred or intolerance of another race or other races.
That's pretty clear and there are a whole raft of ridiculous issues being incorrectly dragged under the banner of racism. The skit was clearly not racist according to the above definition.
Give yourself an uppercut Mr Connick, you pompous imbecile.
Racism needs to be addressed, but lets attack true racism, not humour.
