Strong agreement with your disagreement. I just finished Haidt's The Righteous Mind and observe that rationalists seem to gravitate towards a liberal, individualistic moral foundation, while the rest seem to automatically balance that with, or favor, group binding moral foundations. Thus, we rationalists (and liberals in general) are seen as immoral because of our tendency to disregard others' crucial moral foundations of ingroup/loyalty, authority/respect, purity/sanctity. Thus, this has never been a disagreement over facts at all, but rather, a moral loathing of our very kind.
