Whatever true Conservatism or true Progressivism may be, neither side owns a monopoly on nationalism, traditionalism, morality, etc., however those terms may be defined. Take morality, for example. Perhaps Citizen A's sense of morality is different than Citizen B's sense of morality. Each citizen in this country is free to apply his own moral standards to his own life, but he does not have the right to impose his morals on everyone else in society through the operation of our laws. So long as a citizen's neighbor isn't causing him harm, the citizen should mind his own business. That's called freedom, i.e., LIBERTY & JUSTICE for ALL.
Realize that I am not a believer in Freedom or Liberty. Only Justice, of your stated concepts, carries weight with me. I don't believe that the vast majority of human beings, never mind Americans are truly capable of understanding what Justice and Morality really are. They most certainly have NOTHING to do with Freedom or Liberty. They have EVERYTING to do with Right and Wrong.
Nationalism? I believe all those who identify themselves as "liberal" or "conservative" have most of the same reasons to be proud of country, our accomplishments throughout our history, and our melting pot of citizens. In this country, we're not required to take an oath of loyalty to any Fuhrer, so to speak, out of fear of being whisked away to a death camp.
Nationalism isn't about being Proud of your country, it's about being LOYAL to your country, above all others, under all circumstances. Note that I didn't say loyal to the Government, but to the Nation.
Isolationism? I don't know how you define "isolationism". All persons of every ilk know we can't be the policeman of every country in the world. We don't have the resources to combat social injustice wherever it may exist beyond our borders. Wars of choice, rather than wars of necessity, must be avoided because they will destroy us. We need to address social injustice within the borders of our own country and lead by example.
I define it as.... The world drops off sharply at the border. No people, communications, etc.... into the country. You can leave any time you want, just don't expect to be able to come back.
Socialism? We're not a purely socialist country nor are we a purely capitalist country. We are a nation of laws, not of men. That means government regulation exists for the common good. Throwing out the word "socialism" as some sort of dirty word simply ignores the constitutional structure of our country.
We aren't a nation of laws and haven't been since Abraham Lincoln used the US Constitution as toilet paper in the White House's outhouse in 1861.
