What percentage didn’t admit to it but was lying?
And that is what Marxism promotes. Anything to break up the family unit.
“Abolition of the family! … The bourgeois family will vanish as a matter of course … The bourgeois clap-trap about the family and education, about the hallowed co-relation of parents and child, becomes all the more disgusting.” -Manifesto of the Communist Party, 1848, Chapter II, Karl Marx & Frederick Engels
Karl Marx and Frederick Engels wrote those words in 1848. But the same Marxist philosophy infects America’s powerful teacher unions and leftist officials at all levels of government. Communism was devoted to building a “New Man,” and Marx and Engels saw the nuclear family as an obstacle. Today’s Marxists still believe the same thing.
