Adding that to my list. No screamers or yellers. People can be worked up or upset without trying to establish volume-superiority over you or causing you audible discomfort to match theirs
Nobody yells or screams at me, I will leave/hangup/disconnect + block them thus removing their voluntary abillity to exert that over me
The louder they speak, the less they are and will be heard by me in both present and future
