Good point, but socialists don’t know they are totalitarians.
Of course not. All they want, after all, is what's best for us.
Certainly, that applies to the rank and file of socialism -- the "useful idiots".
But the people who lead the movement know damn good and well what they're really after is power! And to hell with what's best for us -- it's what's in it for them.
Their object is to become totalitarians.
