Excerpt:Â Socialists have historically understood that in order to implement total government, which is what socialism is, institutions that foster freedom and individual independence would have to be weakened. Total government is, after all, against human nature, which is inclined toward individual rights, private ownership, belief in a divine creator, and the sovereignty of nation-states designed to preserve, protect, and defend those natural rights. Besides belief in God, private property, and private industry, the basic family unit is a bulwark of freedom and, therefore, an obstacle to socialism. Developed over millennia, conventional marriage has been universally respected as an essential institution. Marriage represents the most formidable obstacle to government control.
Hence, the totalitarian minded socialist figured out how to undermine marriage.
