The emotional mind cannot be moved by reason. Liberals are very emotional and even anti-reason, much to the same extent as the "creationist" Right wing morons are. It's yet another example of actually becoming that which you espouse to be steadfastly against:
1) I'm not racist, but I refuse to acknowledge racist practices of blacks towards whites.
2) "right-tards" are anti science! but I refuse to acknowledge that IQ and genetics play a role in accomplishment in a western civilized society despite Science baring that out....
