...if you're not riding an equally high wave of popularity and love; perhaps you are not qualified to make these assertions regarding humanity's secret thoughts.

No, the estimated quality of the conclusion should be a function of the quality of the argument and the supporting evidence, not the identity of the arguer. To do otherwise is to commit the classic argument-by-authority or ad-hominem fallacies.

And from the grandparent of this post::

In other words, I suggest that participants (and voters) embrace the view that it is at the least bad manners and at most toxic to the community for a participant to persist in many long comments over many months which tend to take place too many inferential steps away from what most of us comprehend, believe and accept even if that participant is a successful wielder of the material. (ADDED: and for that reason, I will stop using certain supports from evolutionary psychology even though I have long believed and accepted them).

That's rationalizing groupthink. IMO you should speak the truth as best you can, and change your estimated truth based on the arguments you read and the evidence presented, not on guesses about what your audience is willing to listen to.

I hope you were being sarcastic.
