Christians, why the discrimination against Atheists if you can't even live up to your own morals?

oh will you people just stop your bickering for once and give each other a hand instead of a hard time?!! I don't care what you label yourselves as,be it Christian,Atheist,Jew,whatever...someday you hopefully will realize what we all are humans and we are all in this together! geesh It's like listening to a bunch of kids not getting their way and each one determined to be king of the mountain!
