You’d better be ready to look everything up. I recently used the word “thug” and was called a racist. Who knew? So I looked it up. Couldn’t find a dictionary that referred to it as derogatory. Even the Urban Dictionary. Here is an article by a Columbia professor that explained it for me. https://www.npr.org/2015/04/30/403362626/the-racially-charged-meaning-behind-the-word-thug
The fact that I was using the term to refer to gangs in SE Asia that enforce corruption didn’t matter. It is now the equivalent of the N-word apparently and I better never use it again. I’ll have to switch to “ruffians” I guess so the PC police don’t shoot me.
Maybe someone will invent a PC checker, like a spell-checker. I’d buy that!
