Well, yes. Also, central to Christian morality is the element of reciprocity - treat other people the way you would like them to treat you. With the measure you use, so it will be measured to you.
Leftists rather obviously reject this. They will freely judge you, but scream with rage if you judge them.
I am pretty sure that this is the basis of many morality systems. Even Lex Talionis is about this, you get a well as you give, nothing more, nothing less....or something of the same value. Lex Talionis was never about revenge, rather is was about limiting it. The leftists don't even meet the standard of Talionic Law. Probably not even the standards of Draco. For as harsh as Draco was, he brought law and justice as he knew it to Athens, and again accomplished the same as Talion. Remember, they are worse than our early forms of justice. Especially since they are not at all just, they are in fact actively and happily unjust. Worse yet they wear the skin of justice, and use it to insult their victims. They are not only vengeful, but are actively malicious. There can be no atonement, no forgiveness, no settling of debts- only unending damnation.
