Why do Liberals hate Conservatives so much? A quote from Ace:
...researchers determined that "there are five psychological foundations of morality, which we label as harm/care, fairness/reciprocity, ingroup/loyalty, authority/respect, and purity/sanctity." Conservative morality is based on some combination of all five of these moral foundations. There may not be an exact 20% input from each one, but they are all present. Liberal morality is based on only the harm/care and fairness/reciprocity foundations.
"Conservatives have many moral concerns that liberals simply do not recognize as moral concerns... liberals often find it hard to understand why so many of their fellow citizens do not rally around the cause of social justice, and why many Western nations have elected conservative governments in recent years."
Read the whole thing, but the point is well-taken. Libs and Conservatives are coming from different places, with different basic assumptions. I don't think it explains the hatred, though.
