Just read an article in the American Spectator entitled The Liberals’ Reality Problem. In it, author Ron Ross makes the following points about liberals:

• They do not like the fact that self-interest is the prime motivator in human decision making.
• In their minds a market economy leads to an unacceptable level of inequality.
• Because intentions govern their policies, liberals show no interest in looking at evidence. Their denial and disregard of evidence is another reflection of their dislike of reality.
• Their absolute dislike of budgets.
• They’re convinced that humans should be far less plentiful. In terms of global population, the smaller the better.

Check out the article.  It’s a good one.
