Thanks for commenting, Faye. I always find your comments interesting and and an opportunity to think about whatever I've written in a different way. The studies I've cited do seem irrefutable; they actually measured brain activity, and the brain has been pretty well mapped. But while I'm kinda proud I'm a Democrat for reasons made apparent in the article, you're right that we Democrats can't consider ourselves better than other people who aren't Democrats. After all, in our deep history, it may have been the person in the group who was more prone to fight-or-flight who kept the group safe from harm, while the person who was entertaining novel notions was of less use. There are advantages to being fear-based.
