The USA is the result of a kind of ideological movement started by Hobbes and John Locke. It had a basis in Aquinas and Maimonides in terms of natural law. The very essence of American identity is bound up and tied with these thinkers.

What people are complaining about on this blog is the kind of Leftism based on Rousseau.

The difference is vast. But one thing that does stand out is Rousseau does not have any human rights. He has only the General Will. That is his center of gravity. To John Lock the beginning point is the rights of the individual.
But these rights are not more than the Ten Commandments translated from what one  person can not do to another to being right that the individual has not to be stolen from. 

But the difference between rights to get free stuff and rights to be left alone has been obliterated in the USA.
