Most atheism is not the "hard-atheism" of "God doesn't exist and I will not believe in God even if it is proven that God does exist." Most atheism is the "soft-atheism" of "There is no actual evidence for God existing, and I will not believe in God without evidence. If evidence comes forwards, I will believe in God, but until then, I will not." In fact, most atheism could be better described not as "disbelief in God" but rather as "skepticism in God".
But even then, I don't see how "hard-atheism" is any more of a reactionary view than any other religion ("hard-atheism" could be considered a religion due to its beliefs not being founded on factual evidence). If you would care to explain why that is so, I would gladly listen.
In what universe do you live in where the Red Army, which failed to take Western Europe, would be able to stage a trans-oceanic amphibious invasion of the United States and was only deterred by American nuclear weapons?
