OK. I thought I was arguing with another version of "if you're not rational, then you don't value truth". That was presumptuous. And you're right, there is this other category of being rather indifferent or careless with respect to the truth, especially if the truth may be unpleasant or require work. I observe I have a knee jerk reaction to defend the "them" group whenever there is any kind of anti-"other-people" argument... and it is not my intention to be an indiscriminate bleeding-heart defender, so I need to consider this.
