First, there has been a meme campaign about Biden being better than Trump that seems to go out of it’s way to “call out” those of us who are fed up with the behavior of the Democratic establishment (DE). They imply we are fools who don’t comprehend how bad Trump is. The people those memes are directed at don’t really exist. They are a myth put out by the DE to sideline progressives. There has also been a recent wave of right wing bots that perpetuate the myth to further drive the wedge between progressives and the DE. Those bots aren’t going to be convinced, and progressives don’t need to be.
The second is that it is nearly impossible to criticize the DE without getting lectured about how much worse Trump is. Being a tiny bit better than fascist is apparently enough for Democrats privileged enough to not suffer under even Democratic policies. I think this video shows a great example. I try to always mention that Republicans are worse when criticizing Democrats, but that rarely makes a difference.
The third place is from old timers like me who have watched Democrats coddle fascism ever since Reagan. What we are living through now didn’t start with Trump, and it wasn’t just the fault of Republicans. Many of us have been fighting Democratic mediocrity since before most Americans ever heard of Bernie Sanders. The DE is routinely snide and dismissive of the left, even as they fail to grasp the Republican threat. They say the country wants centrists, but run to the left with their rhetoric before every election. In that context, both of the previously mentioned items tend to strike a nerve.
