I'll never forget one time I had an experience in California while disposing of my Great aunt's estate. The man next door was a black man, very nice, but also hyper sensitive and preachy about racism and assumed I was racist because I'm from the south. Anyway, we had a yard sale with my aunt's stuff and he was looking at what he called "Chinese" paintings. I corrected him and told him they were obviously Japanese and not Chinese, and that there's a very distinct difference. He then said with all seriousness, " Chinese, Japanese, it's all the same". I wanted to facepalm at the irony lol
