There is an explanation for this:

Why is it these Leftists always attach themselves to strange occult mysticism? They are what I call the "Religious Left."
They worship for gods those appearances that remain in the brain from the impression of external bodies upon the organs of their senses, which are commonly called ideas, idols, phantasms, conceits, as being representations of those external bodies which cause them, and have nothing in them of reality, no more than there is in the things that seem to stand before us in a dream...
Like the necromancy of the Wellstone funerally, the use of Martin Luther King Day, or constantly invoking the "spirit of the '60's," they attempt to raise spirits of the dead as a totem for worship.
Marxism and their forms of Cultural Marxism are a religion, a collection of cults. In many cases they worship a dead Karl Marx like some (and I stress some) Christians worship a dead Jesus, and not a living God. This is no more apparent than in the practice of enshrinement and regular grooming of Lenin's corpse in the former Soviet Union.
It is similar to the religious fervor associated with the pro-abortion advocacy. The societal practice of abortion is ritual mass murder upon the altars dedicated to idolatrous vanities, a collective human sacrifice to pagan idols.
As is Ms. Parks' association with The Federation of Damanhur (check out their Cultural Marxist statements to preserve primitive, dying cultures), so is the Left properly identified with a confederacy of decievers that, to obtain dominion over men in this present world, endeavour, by dark (meaning also obscure) and erroneous doctrines.
