very well said. However I am not convinced this has much to do with right-leaning politics. It seems, in my experience, it is a human trait we are dealing with and it is independent of politics. If, when you have time, you think about what you have so competently written, I will guess that you will realize that there is no fundamental reason, not one we can think of anyway, why this innate proclivity of ours should depend on our politics. If it does, then we ought to examine why. My best guess is that regardless of our politics we will react similarly. We should be equally receptive to hijacking of our 'outer rational cortex', independent of whether or 'belief' system is ingrained as right or left. If I am not correct here, then we have stumbled upon something quite profound.
A most interesting thing to me is the observation that some individuals are able to quite easily transcend their natural proclivities, where others can only do so with great difficulty. I have thought that education, not job training but education, buttresses our ability to do that. But I don't know if I am correct.
