I asked for quotes from the Communist Manifesto itself, not from self-serving interpretations of it.
That link was just in the first couple of results. You will find many others with consistently similar "self-serving interpretations" regarding the similarities between the central tenets of Communism and American domestic policy during the last century plus. Many. Others.
That America has adopted several tenets of Communism is not really a very controversial thesis with the "classical liberal" or "Patriot" crowd, as far as I've seen. I'm surprised you're not aware of that.
You can go on believing that America hasn't adopted tons of Marxism. I'm sure that's very comforting. But it's pretty clear we have. You can make the argument that it's a watered down version, but to deny the similarities is absurd.
I'm sure it makes you feel like less of a slave that you've paid income tax your entire life, because, hey, at least it's not Communism! LOL!
