I like the brief definition that does sum up the basic tenets of Socialism. It’s been discussed and is still for those willing to learn. Freshman etc.
At some point, people must go beyond the simple definition. But for your purposes, the vagueness of any real expansive definition isn’t needed.
However, because you were drawn into it; the meaning of words are not flexible, sort of like the meaning of words & articles in the constitution? And lesser laws. Are you an Antonin Scalia fan?
