That’s not entirely fair, as the comment simply points out that there seems to be a historical trend of a reflex to reinvent religious structures after abolishing traditional religion. Even in the modern day you can take a look at various rationalist/atheist/anti-theist communities which get dominated by larger-than-life personalities from Dawkins to P.Z. Myers, all the way to LessWrong’s singularitarians reinventing eternal damnation via Roko’s Basilisk. Pointing out that it’s very easy to fall into dictatorship isn’t necessarily an endorsement of one, it just should serve as a caution and as a lesson in humility.
