A few years ago, I seeked out a Chuck Jones cartoon about a dog who sang opera: He grabbed a magician's tailcoat and all hell broke loose.
As a child, I was in stitches as he turned into a little child, a chinaman, a minstrel/blues singer, etc.
But as an adult, I was horrified at how the same characters were so demeaning to others and how inappropriate the content now was.
In concept, there is nothing wrong with being politically correct, as I believe the intent is to unite. Unfortunately, the PC police are very divisive, which has put us in this violent pendulum swing between PC and social pushback.
Not that anyone needs my validation, but being behind the leading edge of political correctness should not make you a pariah. We should own who we are and identify with the good and the bad. Engage with people as equals. As Dennis Miller once said: "Prejudice is stupid. If we just took the time to get to know people in the groups we hate, we could find a perfectly legitimate reason to hate them!"
