IMO the priggishness is baked into American culture, which is descended from cranky puritans and literally defined itself as the most moral (police) force in the world after genociding the original inhabitants of the continent and setting up a culture for billionaires that leaves even qualified and talented workers increasingly insecure about housing and health care.
In reality "woke" has been a hugely convenient way for the US establishment to confine the Left to a ghetto of minority interests, especially about sexuality. Because if the Left rediscovered economic justice as a cause it would cross political boundaries and become a raging wildfire. (See also - Luigi.)
So now we have anti-woke for the wannabe intellectuals, and Q for the useful idiots.
Meanwhile Graham is more outraged - outraged I say - by how annoying feminism etc are than by election interference, raw milk drinkers, and the spread of lunatic propaganda about vaccinations and climate science.
