Is it immoral not to fight religion

That would be peachy keen. If it’s not too much trouble, could you let me have broad idea of the evidence you would use in forming such a belief?

In brief, my position is that I do not believe in god(s) nor a non material, super-natural existence or being(s) . The reason is the lack of empirical evidence, unless something has come up in the last 24 hours and I missed it.
