Luddites and other fearful creatures

My daughter's teacher is a Luddite. Of course, I had to explain the meaning of the word "luddite'' to HER, because, well, she is a 15 year old girl and not privy to all words in the dictionary. Unlike myself, who has been privy but has forgotten all of them now. Except for "luddite", of course. I told her to call her teacher a luddite and see how he took it, but she's afraid of him killing her (something about a pistola), so she is going to tell her friend Jacki who will then call him Luddite and ostensibly be killed by the pistola. Good times.
