"Conservatives" adhere to the idea that everyone has the capability to have good character traits (honesty, responsibility, integrity, self-control, etc.) and they make an effort to exhibit good character themselves in order to prove it. "Liberals" adhere to the idea that everyone need not make an effort to establish good character and excuse poor character (dishonesty, irresponsibility, sloth, drug/alcohol abuse, etc.). Liberals may or may not exhibit good character, but they will always excuse others for behaving poorly. It's all about how humanity is perceived and the difference between good and bad.
