I hardly see how atheism could at all, anywhere, anyhow, be considered a religion.
"Some people think God is an outsized, light-skinned male with a long white beard, sitting on a throne somewhere up there in the sky, busily tallying the fall of every sparrow. Othersfor example Baruch Spinoza and Albert Einsteinconsidered God to be essentially the sum total of the physical laws which describe the universe. I do not know of any compelling evidence for anthropomorphic patriarchs controlling human destiny from some hidden celestial vantage point, but it would be madness to deny the existence of physical laws."-Carl Sagan
"Show me where Christ said "Love thy fellow man, except for the gay ones." Gay people, too, are made in my God's image. I would never worship a homophobic God." -Desmond Tutu
