Leftism is Paganism

Everyone believes in something. Leftists are Pagans, they just don't know it.
Their chief god is Mother Earth, Gaia. Their worship of Gaia drives the twin pillars of irrational modern Leftist thought: Communism and Climate Change. Communism sets the moral axis, Equality is Virtue, Success is Sin. Climate Change provides their Apocalypse Myth.
Cronus and Moloch were the pagan gods of infanticide.
They have a pagan perspective on sex and marriage. All sex acts are good, homosexuality is celebrated, and marriage isn't anything particularly special.
Their prayer is the social media virtue signal.
Their community is the Echo chamber.
Their alms is being for higher taxes.
Their priests are the media talking heads.
Their pilgrimage is the protest and march.
On the gender axis, they are more balanced, and in comparison to the Masculine Western Monotheistic Religions, they more feminine.
Being Pagan, they espouse universal acceptance of all religions and gods to a degree. This puts them in line with Moral Relativism.
