I actually have many friends who are Liberal.  And I understand that they have a very different viewpoint than I do, and those differences are respected.  Then there are the ones who seem to take the position that anyone who doesn't embrace their political ideology must be ignorant, or a racist, or a Nazi, etc.  I was unfriended by one of those latter liberal types yesterday.  Somehow unfriending makes more sense to those Liberals than in trying to sway me with rational, logical, and  persuasive arguments.
