Simple facts are often just ways to avoid looking at complex truths.
I think what is being said is that "socialism" is a mystical thing that sometimes refers to governments, sometimes individuals, sometimes groups, and, in all cases, can be just about anything you want as long as, in the end, it involves more than one person.

There is nothing mystical about the definitions above. Nor any big words or complex truths. Just simple facts that explain things in a simple way.

Socialism is a political ideology which seeks stem runaway inequality caused by capitalism.
You go on and on about Democrats standing up and tooting their horns...but you want them to play the same tune as the Republicans.
