and atheism is not a religion. of course, you use the term atheism mostly in reference to the horrid Chrisitian doctrines. There are other versions of a god that are somewhat less horrid. And there are even Christians who minimize the worst of their essential doctrine, and try to find mostly the good ethical precepts*- which of course are shared by people with other religions and no religion -*such as not killing innocents.Christianity teaches that we are all born wretched sinners, owning an apology for decisions made, without our consent, thousands of years ago. But before we can be redeemed for the crime of being born, God decided that a human sacrifice was necessary.
Atheism is a rejection of this degrading filth, so yes, it would be silly to compare the two.
a pantheistic view is less horrid, since it merely calls the all by the name of God. it is a good replacement for all inferior versions of a God. it does not make all sorts of awful side claims or have a priesthood.
