Having this person talk is a waste of oxygen
Most people will dismiss obvious BS, but there is always a small percentage of the population that will fall victim to the most hare-brained ideas all while telling themselves (and others) how wise they are.
Flat Earthlings, Covid deniers, anti-vaxxers, anti-Sciencers, all have egos in direct opposition to their intellects IME.
So rather than publicly debunking the obvious I suggest we simply disallow it from social media. That'll show them.
