You doubt my good faith; I must doubt yours

Neither of us are acting in bad faith. I think I was fairly straight with "disagree with your implication except for the technical meaning which is an ironic segue". You were fairly clear too. It is just the way people talk.

From that beginning the best outcome we could expect is to end up arguing about definitions of rationality or straight contradictions on whether the known correlations between cognitive traits are 'rationality' related. Why go there?
