Cue up a lot of people who are going to use rhetoric to take make a "reasonable", "non-dogmatic" issue about this topic, while only barely acknowledging sub-conscious prejudice for or against.

I don't have a solution here, I'm sorry. But whenever I read a comment that sounds too cool, even-headed, and rhetorical, I know I'm going to be hit with some contrived hypotheticals and not much supporting data.

I don't know how to address the issue of prejudice. I just dislike it when people engage in discussion and pat themselves on the back for having taken a "reasonable" position. Not that I think arguments should be unreasonable, I simply see in practice that most "reasonable" arguments don't actually illuminate and are simply exercises in rhetoric.
