You should disabuse yourself of the notion that concepts like personal discipline, contentiousness, and integrity are somehow "conservative" values. They are not in either sense of the word conservative.

Certainly from a political standpoint, republicans (or their equivalent in other nations) have often used these concepts against women, minorities, and the mentally ill as a means of shirking their obligation to help their fellow human. In my observation, they never make much of an attempt to live up to them in their own lives. (e.g. YOU are a welfare queen, but I am an entrepreneur who needed to take a government bailout).

On the other hand, if "conservative" means "old-fashioned" to you, then there is also no reason to believe that the people before us were morally superior to us today. My reading of history leads me to believe quite the opposite.
