If you judge atheists and you think that atheists judge you Christians, then you are pretty much contradicting yourself, which is a sin in God's eyes because "all men are created equal."
I don’t judge Christians and their beliefs, so why do you? Thank you for listening to me.
What I find amusing is the difficulties people get themselves into when they start with a premise that all judgment is wrong. You demonstrate this in your own consideration of the issue. You came to a conclusion -- a judgment -- that I've made a mistake. Yet because it is your own conclusion you think nothing of the matter.
The error starts with the false belief that all judgments are wrong. What Jesus actually taught was, "Do not judge according to appearance, but judge with righteous judgment" (John 7:24). Thus I am doing as Jesus commanded when I conclude that atheism is a false system of belief because God declared, "The fool has said in his heart, "There is no God." They are corrupt, They have done abominable works, There is none who does good" (Psalm 14:1). You might disagree with God's view of your belief system, but historical evidence is stacked against you. Atheists as a group do not tend to leave the world in a better place, but that is because their belief system doesn't give them much concern about their fellow men.
