While teaching a class last week, I made the widely-recognized hand gesture (an open circle with the thumb and index finger, with the other 3 fingers loosely or sharphy extended... I'm not sure exactly how mine looks, as it's like muscle memory and I don't consciously think about the exact shape I'm making) while simultaneously saying "okay...". I can't remember the full sentence but it was something related to the math course I'm teaching.
Now I suddenly learn that it means "white power" to some people (some Americans). To make matters even worse, I'm white, and I make a very similar-looking symbol while indicating 3 things (some use the middle 3 fingers for this; but I've always done it the other way) or counting to a number between 3 and 5 with my fingers. Good heavens!
Would I possibly get into administrative trouble for doing this, if a student were to report it?
