"Your denial of the importance of objectivity amounts to announcing your intention to lie to us. No-one should believe anything you say."
-- John McCarthy
"How exactly does one 'alter reality'? If I eat an apple have I altered reality? Or maybe you mean to just give the appearance of altering reality."
-- JoeDad
"Promoting less than maximally accurate beliefs is an act of sabotage. Don't do it to anyone unless you'd also slash their tires."

Those quotes seem rather weak to me. Especially the last one. Armchair psychology, you're worried about your own propensity towards irrationality, so you seek to master it by focusing on irrationality external to you, as by seeking to wipe it out. Kind of analogous to evangelical christianity. I'm not sure rational heroes and irrational villians in a morality play is as valuable to us trying to build our best models of the world, including of various irrationalities as natural phenomena. Whether we should expend effort to convince people not to engage in various irrationalities is an empirical question, and maybe one that has different answers in each instance.
