Christianity and the worship of God is about love. Remove love and you will remove the key ingredient of a civilized society that results in a chaotic world where compassion is foreign and people are treated as “units” to be used (taxed to infinity) by their overlords. Just the way they’d like it.
"We must hate. Hatred is the basis of communism."The communists were all about replacing love with its extreme opposite.
— Lenin
"We hate Christianity and Christians. ... They teach love of one's neighbor and mercy, which is against our principles. Christian love is an obstacle to the development of the revolution ... What we want is hatred; we must know how to hate; only then shall we conquer the universe."
— Anatoly Lunacharsky, first USSR education commissar
