I agree with this point, but would say it differently.
I disagree. I see conservatism as an acceptance of our limitations and an acknoslwedgment that the insitutions and values evolved over many generations will normally be superior to those that are designed for us by people professing some great insight into humanity.
Those who are professing insight into humanity and designing values for Americans today are liberals and the intelligentsia who are practicing cultural Marxism. I don't find these "values" to be superior to the ones my parents and grandparents were taught. True values do not evolve, they are constant and stand up to time.
"There are those who believe that a new modernity demands a new morality. What they fail to consider is the harsh reality that there is no such thing as a new morality. There is only one morality. All else is immorality." --Theodore Roosevelt
