Jezebel has a few things to tell us regarding critical thinking and racism, mostly “keep it simple stupid.” Stop making excuses to believe that there is no racism or that it’s sufficiently over that it can be employed ironically. That ignorance is a failure in critical thinking.
Writers Jim Cooke and elenabo/Shutterstock use a disquotational appeal to truth:
You know how you can tell that black people are still oppressed? Because black people are still oppressed.
The evidence is overwhelming. Even if it were not, irony takes a delicate hand and is almost impossible to deliver from a position of privilege.
Their anger is inspiring but humour is difficult to think about critically. Many of us have no understanding of how it works and why what seems to be a simple pleasure can cause so much harm. Perhaps that is as important a subject for teaching critical thinking as argumentation? Humour can be a hindrance or boon, and understanding the reasoning it involves may help us use it better.
