Your "when even" isn't particularly accurate. Obama was always a relative centrist. It's just that many consider it radical to think that we should do simple things like provide most people with access to healthcare.

The "even" in "even Barack Obama" isn't about him being super far left, then "even" is about the fact a former president has to be the one telling people their tactics aren't working.

And then they go on to ignore his advice because he is insufficiently left. Which ironically proves how prescient his advice is.

The pendulum always swings

> even Barack Obama

I mean, he's not particularly leftist, is he? If anything he represents a pretty centrist liberal (as in Liberalism) position?

If that's the case, then it's a fight that was going to happen sooner or later, because it's not as if progressive opponents were sitting back and letting culture change without protest. If anything, calling out people for bad behavior is a reaction to the realization that a lot of "centrists" were just closet racists, who may not advocate for some form of supremacy or other but sure were donating and voting for it when the opportunity came.
