Robin Williams had that horrible form of dementia, Lewy-Body dementia, besides having Parkinson disease so I wouldn't assign a whole lot of derpness to him yet.
I don't think Bourdain was a derp, in fact he spoke out against the Clinton's in his last interview before his death.
Thanks for that info.
It’s entirely possible that “suicides” happen for multiple reasons. Shutting people up seem high on the list of reasons. The derps shut people up regardless of which side they are/were on.
