The particular neckbeardy, fedora wearing, Sam Harris listening trend of atheism was a pretty clear reaction to the evangelical psychosis of the Bush administration.
Other geriatrics here can attest that the character of Christianity at the time was way different than it is now. These days, the fascists are more "culturally Christian" and avoid overt bible apologism. But back in the day, these people were constantly on TV spewing young earth creationism and other shit, and they were largely taken seriously. It's hard to believe now how much time was spent "debating" evolution back then. The atheist backlash at least affected discourse aesthetically for some time, making these views laughable, which deplatformed a lot of evangelicals or made them hide their power levels on TV.
Some argue that this brand of atheism justifies imperialism. It does so really only in theory. There really is no material basis for atheists in the US to justify an invasion anywhere in the world. The truth is that Christianity is still a far more powerful force for imperialism. Bush said that God told him to invade Iraq. I don't see any president saying anytime soon that the US needs to secularize a country through force.
If fundamentalist and political religiosity were defeated, then belligerent atheism would dissolve, but the reverse is not true.
Overall, it really does seem like people over emphasize this group of internet no-lifers because of the cultural cringe they manifested.
Carl Sagan had a book about that, it was called, "The Demon-Haunted World". It was a best-seller, of course.
That shit shows up on Hexbear quite a lot. It's unexamined colonialist savior ideology. It isn't just arrogant; it's bad for solidarity attempts.
If the PLA had not marched into Tibet, still today they would be living in that demon-haunted world and serving the lamas.
There's a difference between a liberating force and colonial enterprises, and that difference is the difference between driving the Lamas out of Tibet and "Operation Iraqi Freedom" and all the mud hut talk that was presented to the imperial core to justify the plundering.
That shit is also pushed by :my-hero: and his cult, right now, to justify plundering impoverished countries for lithium and other rare earth materials. "They're just living in mud huts being primitive and superstitious! We have science and are coming to save them, and most importantly, they're not using those resources in a way that we prefer!" :so-true:
EDIT: Come to think of it, Ayn Rand herself claimed that First Nations peoples deserved to be slaughtered because they weren't using resources properly and were superstitous and living incorrectly. Your argument's sounding more and more sus the more I think about it. :sus-soviet:
