Truth is one of the pillars of our society. Is it no wonder that the left and Islam have utter contempt of it? These two ideologies which are in bed together are not compatible to American virtues and way of life.
Many things at their best are a search for the truth. This includes reporting, historical analysis, a judicial system, and science. Christianity and Judaism value truth. Judeo-Christian values underlie western civilization. The left and Islam use the fruits of western civilization to attack it.
