To understand modern America, you have to understand the main players. They no longer break simply into left and right, liberal or conservative.
The three religions of modern America are Old-Stock Christianity (American Boomerism, Constitutionalism, Evangelical Christianity, etc,) Wokeism, and anti-Wokeism (basically the alt-right).
(If the lack of explicit deities in two of these bothers you, replace “religion” with “belief system.” Note that Wokeists and anti-Wokeists can also be members of various religious groups, eg, Universalist Unitarians, but this is not critical for understanding their motivations.)
Wokeism is an explicit argument against Old-Stock Christianity (old conservatism is weak to progressive arguments since prog arguments are specifically designed to respond to old conservatism, which was more culturally powerful in the past). In Wokeism, the greatest of sins is racism (followed by the other ‘isms). Wokeists have converted Christianity’s original sin of illicit fruit consumption into the original sin of racism.
To Wokeists, Christians are pagans who have not yet accepted the new religion. Anti-Wokeists, by contrast, are apostates who have rejected the new religion.
The latter are considered far worse than the former. Pagans can be converted to the True Way, but apostates cannot: they have already explicitly rejected it.
To the Old-Stock Christians, the Wokeists are a confusing extension of their religion–maybe just a youthful, semi-heretical phase (while the anti-wokeists are invisible and inexplicable).
By contrast, Anti-Wokeists (including the alt-right) are making explicit arguments against Wokeism. Thus they are to Wokeism as Wokeism is to Christianity.
