The family is one of the things that Karl Marx wanted to abolish, because it gets in the way of communist revolution. A person with a family wants to provide for it and seek a better lifestyle, all capitalist goals.
Other things he wanted to abolish include private property, individuality, religion, morality, nations, and history. There are a lot of people running around in the US who are devout followers of Marx. I recently posted about an author who wrote articles in a teen magazine telling them how we needed to abolish private property, the police, prisons, etc. We've seen people trying to erase US history by toppling statues and defacing monuments. The idea behind the national anthem is to unify us, but it is no longer good for that. They only play it now so that they can protest it.
