"atheism, taken seriously, is right-wing" The exact opposite is true, and the fact that the overwhelming majority of Atheists are Left-wing actually demonstrates why. Atheism is the wrecking ball that demolishes vertical hierarchies and exchanges them for the horizontal mediocrity of egalitarian Wokeism. You don't get Progressivism without first bulldozing traditional conceptions of things like sacredness and transcendence. To be Right-wing is to accept a higher moral order, not to rebel against it, much less deny that it exists in the first place. This is just a nihilistic will to power dressed up as being Right-wing, which is really no different than the nihilistic hedonism of the Left.
