As I see it, there are three types of liberals.
I live in a heavily-Democrat area. Some of my acquaintances are old-fashioned blue dog Democrats. They vote straight Democrat because their grandfathers did. Their votes hurt the country. But they also proudly put out the flag on the Fourth of July. These folks can be reached by careful and often indirect arguments.
Then there are the true progressives. As you noted, many of them are communist and racist. You can’t discuss anything with them. We must try to block their every move.
But there are also those progressives who are that way only because of relentless liberal propaganda. They too damage the country. But they are not cemented into their positions. Perhaps another Reagan could reach them.
See my post above - agree.

There is a fourth type. Those who know its BS but think they have something to gain by propagating/going along with it, like the Fred Kinnan character in “Atlas Shrugged”.
The primary beneficiaries of a socialist program are the socialist politicians.
The secondary beneficiaries are the bureaucracies and contractors that support the programs. The tertiary beneficiaries are the supposed recipients.
The primary characteristic of a socialist politician is being a consummate liar.
