Atheists being moral or immoral has nothing to do with believing in a god. I suggest that I'm more moral than you and it doesn't depend on any god.Not true. Atheism proceeds on the basis that the needs of individuals and society in general do not go beyond the satisfaction of material needs and primitive instincts. Atheists see no distinction between good and evil, no morality or any other kind of value, save pleasure.
Atheists believe that love is only an elctro-chemical reaction in the brain.
Actually that's pretty accurate for all humans and animals.
Do you really want to go there? Does a person still love when he's dead? would you suggest that his soul does?
