A Lefty foundation is inherently unstable–they are NOT empirically rooted in what has been shown to work but are blown about by whatever wind of trendy Lefty doctrine happens to come along. More on that soon…
So when the crap finally hits the fan, they can only turn their anger onto each other. They have LONG belittled anyone on the Right, so the only thing left is to make “villains” out of former allies.
And we have also long seen that historically in Lefty governments. suddenly a former ally is no longer “woke” enough. It is so common as to be a meme, something of a cliché.
THIS is Leftism, comrade!
