No there isn't an end to "words that hurt". There is simply no limit to the currently ongoing race to be offended. Hence the "microaggressions" etc. There is no greater attempt at global intolerance than the "woke movement". This entire country has raised behaving like a spoiled self-important child to a national pasttime.
I am an Eastern European Jew. Majority of my family died in the Holocaust or fighting the Nazis. But I enjoy a good Jew joke as much as anyone else. I had a longtime German friend who loved Nazi jokes. I laughted. I have friends who are Asian, Indian, Black. You know what - we can and do make fun of each other's cultures. It seems that I recognize that there is a subtlety to human communication, something that seems to be utterly lost from the US politics. I also recognize that the safety of free speech is FAR more important than any specific person or group's sense of butthurt enthusiasm.
I just hope that this Ouroboros eats itself before it's too late.
