There are "things you can't say".[1] You can be right, and your message can be harmless but the way you communicate it comes so close to a cultural taboo button that it requires too much extra effort not to be misunderstood. You just probably shouldn't go there. It will cause misunderstanding. Its kind of like having a thick "cultural accent".
For example, I used to, but do not now, ever use the word "niggle". Its just too much work.
