I haven't read all the replies in full so apologies if I'm repeating others.
Just wanted to answer your initial question and say that I wouldn't think not reacting / fighting back would worsen my PTSD. In fact, it'd be quite the opposite for me. I find the idea of escalating any sort of confronting situation like that only more triggering and upsetting because it doesn't contain nor control things which is important in maintaining stability. And so it would probably be a PTSD response of mine to fawn into submission when shouted at, especially if I were already zoned out / in freeze mode. And your husband's very respectful response points to this possibility. Or does he always use "Sir" when conversing with strangers?
