I don't think it's a rational method to treat people differently, as inherently less rational, when they seem resentful.

Thank you for this analysis, it made me think more about my motivations and their validity. I believe that my decision to permanently disengage from discussions with some people is based on the futility of such discussions in the past, not on the specific reasons they are futile. At some point I simply decide to cut my losses.

There's actually good reason for the broader meaning of "ax to grind." Any special stake is a bias.

Indeed, present company not excluded. The question is whether it permanently prevents the ax-grinder from listening. EY, too, has his share of unacknowledged irrationalities, but both his status and his ability to listen and to provide insights makes engaging him in a discussion a rewarding, if sometimes frustrating experience.

I don't not know why srdiamond's need to bash SI is so entrenched, and whether it can be remedied to a degree where he is once again worth talking to, so at this point it is instrumentally rational for me to avoid replying to him.
