Anybody that thinks the MAGA movement and Trump are "authoritarian" are politically ignorant.
The Leftist cadre will not quit, because their movement is built on racism, lies, hate and violence. Their entire philosophy is one of hate.
An accusation from the Left is an admission they do it themselves.
If the Left opposes a policy, that policy is generally good for America. If they support a policy, its good for them and bad for America.
