CMV: The Left is now the guardian of traditional values in our society, not the Right.

The Republican party's idea of "traditional values" is built around Christianity and a golden age that never existed. The true values our society is based on are the Renaissance, anti-monarchist revolution, a capitalist sense of fairness, and tolerance for individual liberties.

The Renaissance was a movement away from dogma. It taught that all ideas can and should be questioned. It led to the downfall of the monarchies and great rebirths like in America and France (Life, Liberty, and the Pursuit of Happiness/Fraternity). Equal citizens in a democracy.

Capitalism promoted a sense of fairplay and hard work being rewarded. Wages, individual property, and rule of law all developed out of this democracy/capitalism alliance. At the foundation of this is individual liberty.

People may act as they please, while not hurting others. All of these values are values of the Left. When a conservative says "men cannot marry men, because that is not traditional" I would counter that letting grown men do what they wish is a foundation of our society.

If someone says that Christianity has long opposed abortion, I would counter that the right to an individual and a medical professional to make their own decisions is more important.

Drug legalization? Liberty and personal choice.

Religious iconography and language in politics? Archaic like the trappings of monarchy. (I'm not trying to insult religion, but rather enforce the separation of church and state which was a key feature of both the US and French revolutions).

Creationism and other dogma in school? Only if they can be freely criticized.

So it is the Left that is trying to protect the foundations of our society and morality, Western in general and American in particular. The Right is seeking to change society, to "reform" it into something fitting their ideal.

But which is counter to our shared values and heritage.

TL:DR Liberal values have been our guiding light for 300 years, and reactionary attempts to change that are continuously failing.

On the flip side, a goodly fraction of the Left does seem to currently be going down a dark path of (a least socially) censoring non-politically-correct speech, restricting religious liberty, and banning weapons of self-defense. 

All of which are classical Liberal values of the most paramount importance.
