I've been trying to do roughly that, though focusing more on the "smart and highly articulate" aspect and dropping "emotional mockery". When I read someone taking cheap shots at a position I might hold, I mostly find the writer childish and annoying, I don't see how reading more of that would improve my rationality. It doesn't really hurt my feelings, unlike some commenters here, so I guess different people need to be prodded in different ways.

For smart and articulate writers with a rationalist vibe, I would recommend Mencius Moldbug (posts are articulate but unfortunately quite long; advocates monarchy, colonialism and slavery) and Noam Chomsky. Any recommendations of smart, articulate and "extreme" writers whose views are far from those two?
