Some times a person who I admire for being super smart and an educator says something so stupid that it changes my perception about them fundamentally like with Neil deGrasse Tyson now https://twitter.com/neiltyson/status/1158074774297468928 or Richard Dawkins back in 2011 https://freethoughtblogs.com/pharyngula/2018/06/28/dawkins-and-dear-muslima/

This leads to two important thoughts:

1. Even a superstar scientist has a brain fart sometimes, they're still only human
2. Just because they're mega competent in one science field doesn't make them automatically competent in other fields
