You now have atheists who believe God promised Israel to Jewish people; I'm guessing having a branch of atheism that believes in God is kind of like having different forms of communism?
Some communists are Marxist-Leninist, others are Stalinists, and some atheists believe in God; I guess it's just a modern sect of atheism.
It's like that meme "I'm a vegan, I eat meat, we exist", but for real.
