First of all, if a parent makes a demeaning comment about your appearance, responses such as “Really? I’ll need to pay better attention next time” or making a pleasant comment about the parent’s appearance are not "noncommittal" responses.
And if you act out of annoyance as opposed to outright anger, the above comments are going to come across as sarcastic and the parent WILL know that you are angry.
I totally agree with you here. The best response is to hit the IGNORE button (NO response) so no supply is given. No response IS a response but doesn't open that door giving them something to respond to. They ALWAYS have to have the last nasty word anyway, so that would just draw it out so you'd have to hear MORE nasty words. I also think anyone one the PD Spectrum likely has a mix of them. For instance, my AS, who is a N, lacks both guilt AND empathy so likely also has the sociopath PD going on, too.
