The left is not rational and therefore never thinks. Instead it acts on “faith” — the faith that even though socialism has never worked that this time it will.
But it cannot work because it contradicts human nature of acting in ones’ own self interest.
See my post Bill Maher says liberals are “faith-based” for my “pithy comment” on the topic of the “liberal faith.”
I lump all leftists as socialists, not because I am calling them a name, but because it is in fact a synonym for “leftist.”
Socialism given enough time eventually transforms into totalitarianism.
