Anti-conservatism is anti-intellectualism
A good friend of mine sent me a link to a piece that contained every bigoted false claim in the book that progressive secular leftists use to smear traditionalists, Jews and Christians. Of course, only those who aren't aware of history and the use of such smears, which are nothing more than discredited cliches, actually believe such nonsense. My friend asked me, "Does part of conservatism stand against reason in the sense of being simply anti-intellectual?".
To answer my friend's question I said, "Let me be clear; anti-conservatism is anti-intellectualism". Why?
American Conservatism demands that we look at our history and traditions to use them as a guide. To ascertain works and what doesn't in order to have the happiest and healthiest society we can while recognizing that man's nature is flawed and that society will never be perfect.
Leftists, by and large, believe that rationality must be imposed from above. They believe in a rule of the elite (oligarchy) over the "ignorant masses". The believe that freedom leaves too much to chance. This kind of thinking is what our Founders, Alexis de Tocqueville and traditional American conservatives would call out as tyrannical. The progressive secular left believes that our traditions, Biblical codes, and history are merely mysticism (anti-intellectualism); thus they believe that 6,000 years of human experience means nothing now that they are here to enlighten us.
The left even rejects Aristotle's Law of Identity, they believe that truth is fungible, relative to ones own ideology, and that there are no truths that are self evident.
The left pushes for top down government and central planning for our economy and society, a plan and philosophy that has failed every time it has been tried; often with massive bloodshed to boot. Even in cases where there was not much bloodshed there was still a large amount of human suffering. We see this in Western Europe even now, and we see more suffering here at home as a result of our own dabbling in leftism.
We have seen study after study show that people are more free and have more wealth when they live in a society with the the Judea/Christian ethic.
Those who push Marxism/Leftism/Utopianism/Socialism/Communism/Progressivism or whatever one may wish to call it are selling a defective product and use deceptive advertising to sell it.
