Quora's culture is odd in general. Writing "authoritative" (even they're just LARPing as an expert) is basically why people go there in the first place. It's not uncommon to read something egregiously inaccurate written as indisputable fact. Good examples can be found in anything to do with history.

On a funny note, Jordan Peterson used to be a well known Quora answer writer prior to his current career as an internet celebrity. Source: https://www.quora.com/profile/Jordan-B-Peterson
