First, what does a judge do? A judge decides whether someone has followed or broken the law in cases where it is not clear which is true. Second, what is the law? The law is the set of rules that a country or other political group has decided everyone will live by.
Now, here is the key problem with liberal judges. Liberal judges try to change the rules in the middle of the game. It would be like you telling your little boy, “Don’t drink the pop,” then spanking them because they did not drink the pop. Your little boy would be angry with you and rightly so. So:
Liberal judges punish law-abiding citizens and reward the guilty.
