Even setting that crowd aside, almost every time I see somebody puffed up about how "rational" they are it turns out to involve a vigorous avoidance of the values they're working from.
I know somebody who says that doing debate in high school and college was terrible for him because it trained him to always argue his point but never to question it. For example, at the time he thought of himself as supremely rational even as he'd make a strong case for why he shouldn't quit smoking. It was only much later that he could admit that was his addiction and his ego talking.
Oh wow, that's amazing. The need to be verbally right and perfect no matter the cost is such a curse, so blinding. I hope they all get free of it someday.
