The problem with Alinsky’s tactics is that they undermine the decorum that makes an Anglosphere nation work. You might win with such tactics, but upon winning, you’ve gained control of a society where dog eat dog is back in charge. And the odds are long that you will end up consumed in such a world. The fact that so many in the Democratic Party use these tactics has weakened them for rational debate and leaves them wide open for violent counterattacks when they’re opponents give up on debate and strike back.
The radicals who now run the Demonrat Party are not in the least interested in “rational debate,” any more than Muslims are interested in religious tolerance and free choice. They want to deconstruct our society, then run the country as a one-party dictatorship, as Marxists always do.
