People tend to blur the lines of any and everthing today. Stereotypes become mannerisms and vice versa. If there's proof of what's being said, then it's not a stereotype, yet some people don't get that.
What is being done is grooming society to further dilute the truth in order to further ignore things that make people look bad or feel uncomfortable.
Actually, a stereotype is grouping EVERYONE in that group a certain way (typically negative) rather than just being away that that's the predominant action or belief among a group of people. The key is to look for the good in each person and/or group and work outward from there. We all have bad aspects of our lives and societies and should be willing to fix them. But we should also be able to make fun of ourselves at the same time without malice.
That's how most comedy is, but today they have to really be careful about jokes they tell which kills the craft. I can only imagine the flack that Richard Pryor or George Carlin would get today.
