I had wondered the very same thing years ago. One of the things I came to realize that seems to be lost by some people, is that conservative values tend to be traditional values. What that means is also one of the reasons the word neocon developed due to every changing "values". One of the things that separated national socialism versus a global version of communism was that one aspect tied it with the values of their sovereign nation over a worldly rule. Germany was for Germany which is at odds of a global form of communism even though both forms of government were socialist-like in nature.

One of things you might ask yourself is what values are generally viewed as conservative? That may very from place to place. A person who holds traditionally values in the United States may see things from a perspective from generations that grew out of constitutional republic of the United States versus another region of the world that stemmed from corruption and wars and all kinds of entities attempts to rise to power. In one regard, the United States is sovereign country from it's beginnings, but in way that didn't arise from the same circumstances as Nazi Germany. So, when I see this in particular it seems to be either mud slinging politics or influence from foreign politics who don't understand the origins of the United States (which was far from perfect but was not Nazi Germany).

The other thing that muddies up the water is that fact that the values and social norms of society seems to always be changing. The United States was for the most part, founded by people of Christian faith. Whether or not you are Christian or read the bible or not, one of things that seems to occur (moving the goal post of society) is people that "do what is right in their own eyes", a good lesson from the Book of Judges. The problem with doing what is right in your own eyes versus having an absolute moral authority is that the next person/ or group in power sees things differently than you, and society is always adapting to new and changing social norms, which can (sometimes dangerously) become the traditional values for some that are raised in it can create more and more complicated social problems through time.
