Are all terms related to mental illness or retardation that were later colloquialised to mean something negative in general also banned? Because that’s a long list: Demented, crazy, stupid, obtuse, insane, manic, hysteric, dumb, impulsive, ***, unintelligent, mental...and the list goes on.
Btw, “***” is just the latest of a long list of words pertaining to (amongst other) a human condition seen as negative. The word was chosen to cause the least offense and stigma possible (it literally means delayed in technical jargon), and believe me, whatever new word or euphemism is adopted instead will become equally “tainted”. However, there is a fact that some actions or people are less intelligent than others, and it’s commonly found (mostly subjective) and therefore will have a word associated with it. So are we now not allowed to label anything as less than optimal and/or counterproductive, or do we just shun certain words which are deemed “offensive” by any group or individuals? Also, I highly doubt the OP wished to disparage people diagnosed with mental retardation, and I think everyone knows that. Context matters more than words themselves.
On topic: The stage will be madness (no offense, really) and I think CF might suffer as he seems to revel in long wars of attrition being the “last man standing” and profit from his extreme endurance. Valverde, Barguil or Porte to win.
