You are wrong.
The term you are looking for is communism, not socialism.
Nordic countries are practicing Democratic Socialism.
DSA is not communist.
Why are you spreading this crap when it takes 2 neurons and a few searches to find out you are wrong?
You are mistaking Democratic Socialism (of DSA fame) for Social Democracy practiced by Nordic countries.
