In The Manifesto of the Communist Party https://books.google.com/books?id=s2iEeCJAlusC , Marx/Engels write:(Page 39)

Abolition of the family! Even the most radical flare up at this infamous proposal of the Communists On what foundation is the present family the bourgeois family based On capital on private gain In its completely developed form this family exists only among the bourgeoisie But this state of things finds its complement in the practical absence of the family among the proletarians and in public prostitution.

This is written as a response to objections by "bourgeoisie" detractors, though it's not exactly written as a complete refutation of the charge. I can't help but be curious as to what the exact charges were and how they were actually written/said, but it's likely in German if not completely lost in the sands of time altogether. Nonetheless, this is vague to me. Unreliable and old. I say rely on something more modern, and more concrete. The communist goals of 1963 are a good place to start: (Click here for text and audio https://www.popmodal.com/video/9665/Com ... iet-Anthem )

40. Discredit the family as an institution. Encourage promiscuity and easy divorce.

And there are other goals which also contribute to making this goal a reality. But is this the only one? How about something even even more current? Written in 2007, The Coming Insurrection by the Invisible Committee says the following:

Form communes
Communes come into being when people find each other, get on with each other, and decide on a common path. The commune is perhaps what gets decided at the very moment when we would normally part ways. It's the joy of an encounter that survives its expected end. It's what makes us say “we,” and makes that an event. What's strange isn't that people who are attuned to each other form communes, but that they remain separated. Why shouldn't communes proliferate everywhere? In every factory, every street, every village, every school. At long last, the reign of the base committees! Communes that accept being what they are, where they are. And if possible, a multiplicity of communes that will displace the institutions of society: family, school, union, sports club, etc. Communes that aren't afraid, beyond their specifically political activities, to organize themselves for the material and moral survival of each of their members and of all those around them who remain adrift. Communes that would not define themselves – as collectives tend to do – by what's inside and what's outside them, but by the density of the ties at their core. Not by their membership, but by the spirit that animates them.

Communes should displace the family. Looks like the German 'bourgeoisie' that Marx and Engels objected to were right all along, and when we were told that this book calls for the destruction of the family, (here https://www.foxnews.com/story/0,2933,601643,00.html )we were given accurate information. It's all in the wording. Two notes about this book. I used two links because both indicate that The Coming Insurrection is public domain, which would make sense given that it was used in a court case. Whoever uploaded Coming Insurrection in that PDF file didn't put the pages in order. Page 67 of the book(page numbers bottom right) appears on the PDF's page #25.
I hope that those of you who have run into my blog before are starting to realize that there are answers to all of this - It took me a while to figure that out too. How do these people communicate with each other? How do they know who is who? What do these people believe, have they ever written it down? Where does all this come from? We don't want to live under the authoritarian thumb of progressivism, communism, socialism, or any other. But if you're going to fight this, you're going to need answers. Because anybody can refute a simple charge into being a baseless charge.
But not if you have their own words on your side. Changes everything when you have something more than anecdotes. It just requires someone to go digging and then once the answers are found, tell people what page numbers to look at.

No matter what poiticians and phylosophers say the trdition of family is dying out.

It's not really 'dying out' as a matter of course, of events that are just happening. It's being systematically targeted and destroyed. The Kulaks did not just 'die out. The dinosaurs 'died out'. Big difference.
