"Socialism" has become a dirty word in the US largely due to historical reasons involving the cold war.

As a result its definition in the minds of Americans is very often something completely different than the actual definition.

Basically it's just the evolution of language. They're two different words now, depending which side of the Atlantic you're on.

Yes, because in America, both Joe Biden and Bernie Sanders are labeled “socialists” even though they are on opposite ends of the political left. Joe Biden doesn’t even support Medicare for All, the most socialist healthcare idea we have; instead, he pushes the ACA, which was originally a Federalist Society (read conservative capitalists) healthcare plan implemented by a Republican governor in Massachusetts. But somehow Joe Biden is a “socialist”.
