I do, but for a different reason. Disrespecting a teacher entitles a student to suspension in my book, followed by a spanking at home by the parents to emphasize the point. A spitball directed at the teacher, a tack on their chair, foul language, talking back, physical contact of any sort, or pointing at them and saying, "Bang bang, you're dead" is grounds in my book.
Or, three whacks across an open palm with a half-inch diameter 42" wooden pointer by the teacher is also acceptable. (Yes, I went to Catholic grade school taught by nuns.) But, since that is no longer allowed, a three day suspension is what it has to be.
Too bad. I thought the old way was better. At a number of levels.
