>history shows often morphs into fascism (lots of Bernie voters went MAGA)

This is FUD that is very specifically DNC coded. The extremely plutocratic DNC-linked propaganda outlets that fed this absolute nonsense peddled all sorts of other nonsense conspiracy theories too (e.g. Russiagate, not that that one did them any good...).

Every single one of the DNC supporters implicitly backed fascism and Nazi-style genocide in Gaza by lending their support to the same DNC that backed it (even if they did not agree with it).

Again, plutocracy at work.

They paved the way for the equally depraved MAGA fascism that supplanted them. Trying to pin it instead on a bunch of powerless progressives, some of whom voted for "not more of the same shit" plumbs the very deepest wells of moral depravity. It is deeply shameful.
