What is "bad" religion?  

I read one respondent saying that Christianity is bad religion just because he is an atheist. I really was appalled because he has no right to jusge what is bad religion or what's not? Or whatever he is talking about. I respect the views of atheists. I just hope they stop saying what Christians believe as "friggin ' crap" and "bad" and it's only a belief to make Christians feel comforted. God for us is way beyonf themeaning of "comfort" ---so why are they saying this? Is Christianity so bad because God or Jesus teaches us to be selfish, greedy, evil and malicious? Or does Jesus teaches us to achieve the wrath of ire and life to sin? Does Jeus teaches us to sacrifice ourselves to overcome good for evil? Maybe if Jesus teaches us these, then maybe Christianity is bad religion. It deeply hurts me so much because I love Jesus so much. I just hope these atheists just respect our views. If they don't want to believe in God, then just leave us alone. If they hate God , why question us why we believe in what they hate. What is bad religion, anyway?
