Why aren't we allowed to call insane people nutters on this site?

I work with people with severe learning disabilities in England. These people already have hard lives and live with the stigma of being labelled because of their disability and even ridiculed in the street for it. Society is slowly trying to erase that stigma and allow people with disabilities to be treated fairly and without having to put up with abuse (and they ARE still abused badly). They're called nutters, loonys r****ds, spaz, and laughed at. This can really bring them down and hurts them significantly. It makes their lives even harder.

Stopping the use of such words isn't woke or politically correct (words like woke are themselves terms of ridicule and disdain, designed to continue the status quo). Stopping the blithe use of such derogatory slang words like "nutters" is just common decency and an attempt to simply let these people live their lives without being ridiculed, which I think you'll agree is a good thing.
