Polytheism is better for humans and society than monotheism is.
Polytheism, such as Hinduism, Shinto, 9 Divines, Faith of the 7, etc, teaches you to honor and respect multiple powers. This broadens your ability to respect other people's choices. You worship a different deity than me? So do a lot of people, even ones in the same religion, and it's taught to not be a problem.
Monotheism, like Christianity, Judaism, Islam, etc, teaches you to honor and respect 1 singular entity. This narrows your ability to respect other people's choices. You worship a different deity than me? Our religion teaches there is only 1 god, and therefore they are also your god whether you believe it or not.
