What’s your goal in confronting those who criticize the Democrats? You can’t shield them from criticism by wagging your finger at people with legitimate grievances and insisting that they’re helping Trump win. Again, if you want to play the blame game it can go either way; you can blame the leftists who criticize Democrats or blame the Democrats for failing to address the concerns of their own base.

Trump and his cronies have been drowning in criticism since he first entered politics and he’s able to shrug it off like a minor annoyance because he’s done the work of building a strong base of support. He appeals to both the material and immaterial interests of his base and is responsive to their desires (to the dismay of anyone with any semblance of sanity).

Meanwhile the Democrats treat their base with contempt, never responding to their concerns, and abandoning them like so much garbage when they thought it was strategically prudent. They make themselves vulnerable to the kind of propaganda you’re talking about by refusing to engage in even the slightest appeal to those who critique them from the left.
