You’re putting words in my mouth now. I’m not ignorant of the history of how the left-wing ideologues took over both parties (as mentioned in Goal #15 of the 45 communist goals for the USA), but the Civil War was not the point where the culmination occurred. (And as for the Civil War, I find Dinesh D’Souza’s assessment of the causes to be the most factual, FTR.)
I could care less about the causes of the Civil War. It’s the effects that are driving us into an oligarchy. Ideologies are ALL just different forms/subsets of an oligarchy. Democracy (mob rule) is merely a transition from a Republic (Rule of Law) to an oligarchy (Rule by a few). Throughout history oligarchies are by far the most prevalent form of government but from time to time radicals rise up and create the ebb and flow of history like tides. The Constitution was unique in history. To protect the individual from government was unheard of but we lost it and now we’re on the outgoing tide.
