Unfortunately, following one's world-view instead of reason is not limited to liberals. It may anger some, but right here on this forum, all one need do is read one of the myriad pro Duncan Hunter threads to see the same thing.
It hardly matters that Hunter has as much chance of becoming President as Bugs Bunny, many will defend him and tear down others who MIGHT have a shot, and call it 'convictions', which is a joke.
...and read the tag line.
What's your problem with Bugs Bunny?
Oh, forgive me great one. I ignored your tagline and now must pay the penalty.
I do agree that we can all get baggy about things, but I think Liberals are beyond reason. The smallest chink in their world view makes them crazy. Facts are the chinks that are constantly threatening their neatly constructed reality, which is why they will do anything to avoid them.
