I think the whole takeover could be summarized into fewer points than the 45 listed.
1) Diminish distinction between private and public ownership and enterprise.
2) Use government as a means of enforcing and defining traditionally moral or religious principles
3) Treat as many traditions as possible as violations of human rights.
4) Justify action against freedom of speech, freedom of religion, and freedom of the press under the argument that they constitute a violation of human rights.
5) Diminish distinction between political parties, seek evolution or overthrow into a one-party system.
So right there, I have it summarized down to six basic points. My primary disagreement with Cleon Skousen and the Congressional Summary is about how insidious communism would need to be in order to takeover, and my emphasis is primarily on human rights, because if we ever come to communism, it is most likely through the voice of our own electorate, and judicial action that this happens. I would also state that most of these arguments are a little old and outdated by now, but overall, still a few good points out of the whole 45.
