There is no orthodoxy because for orthodoxy you need stable goal posts, which they do not have. Instead what I think we’ve got is Lefties who think they know how things should work and who want things to be a certain way. When reality doesn’t line up they keep changing the rules in order to effect the desired outcome. This is how brain drains happen. There is a contingent of resentful haters in this group that are getting another larger group of suckers to support their ever changing demands. I think we can compare that group to a community that supports witch hunts. Witch hunts have burned out in some parts of the world while they are still going strong in others. Your mileage will vary, but in some cases, like the sanctimonious “In This House We Believe…” signs, you are probably looking at a fad I think, which will have a shorter sell by date than most witch hunts since its all about being fashionable.
But yeah no, there is no orthodoxy because to be orthodox you need a stable set of rules.
I think the orthodoxy of the left is authoritative statism, communism or whatever you want to call it.
All the crazy things that keep changing seem to be part of their tactic to destabilize society. I think those are just the tools, not the orthodoxy. The loony “useful idiots” will be of no use to the leftist elites if they gain total control.
