Atheism doesn't compel anyone to do anything. It isn't an physical object therefore cannot perform any action. Our actions are controlled by our brains, just like anything else. God or Islam or Christianity doesn't compel either. Priests, vicars and imams do.
For me, The biggest Biblical contradiction is this:
''Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth. Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me''
Exodus 20:4-5
I am a jealous god? Isn't that one of the seven deadly sins? Oh dear me. And even worse... He's not going to punish the person who dislikes him... but his Children, and his children's children? Without trail? Oh, so much mercy God... How merciful you really are.
