Back channels would be one way, but then how to verify the back channel? Sibling "I know and your dumb" response not very illuminating here.

My ongoing experience is that this question is never asked in good faith so please don't misunderstand me.

What I am saying is: I think you know and you have an agenda.

If you truly don't know then this is really something you should know if you are doing the job you are saying you are doing.

To use an analogy: I would not waste my time explaining how type systems work to someone who is arguing rabidly against them in an online forum.

If they care then it's something that is so important they should actually go out and educate themselves before getting into conversations about it.
