Thanks. Where can I find out the credentials of who wrote that answer? Also, as I asked before, how do I know where this theory fits in the domain of accepted theories?

> It has very high standards for answers (as you can see several times a day when a the mods nuke an entire thread for not being good enough):

I'll point out that this practice indicates nothing about the quality; it depends on the mods and not on the quality. If the mods' taste happens to correlate with quality, only then would it result in higher quality comments. For example, mods in a forum that promotes conspiracy theories might also delete threads that don't match their definition of 'quality'.

I'm a little concerned that the parent comment might represent a Reddit theory of accuracy, quality and scholarship, but not the real thing.
