It is, however, a hilariously ironic notion that atheism fails where Christianity succeeds: being appropriated by the far-right to spread bigotry and fascism.

I would argue that it’s not funny or ironic. The right is defined by their pursuit of consolidating power and authority at all costs. Anything and everything is a resource to exploited toward advancing their selfish misanthropic ends. They will appropriate anything and vilify what they can’t successfully appropriate. This isn’t irony, it’s a core tenet of rightism.
