Can you think of anyone on the left who has described Charles Murray as "a good person trying hard to help"? He has been repeatedly denounced as virtually the devil incarnate -- far more often than anyone has tried seriously to refute his facts.
Such treatment is not reserved solely for Murray. Liberal writer Andrew Hacker spoke more sweepingly when he said, "conservatives don't really care whether black Americans are happy or unhappy."
Even in the midst of an election campaign against the British Labour Party, when Winston Churchill said that there would be dire consequences if his opponents won, he said that this was because "they do not see where their theories are leading them."
But, in an earlier campaign, Churchill's opponent said that he looked upon Churchill "as such a personal force for evil that I would take up the fight against him with a whole heart."
Examples of this asymmetry between those on opposite sides of the ideological divide could be multiplied almost without limit. It is not solely a matter of individual personality differences.
The vision of the left is not just a vision of the world. For many, it is also a vision of themselves -- a very flattering vision of people trying to save the planet, rescue the exploited, create "social justice" and otherwise be on the side of the angels. This is an exalting vision that few are ready to give up, or to risk on a roll of the dice, which is what submitting it to the test of factual evidence amounts to. Maybe that is why there are so many fact-free arguments on the left, whether on gun control, minimum wages, or innumerable other issues -- and why they react so viscerally to those who challenge their vision.
