I agree with this. Among the atheists here there is , as with the religious believers, a range of views. One might place them on a "Dawkins spectrum" ranging from the younger Dawkins, representing the fundamentalists, tilting at windmills and naïve strawman representations of religion, to the older Dawkins, who seems to have realised that being shrill and angry all the time is off-putting, counterproductive and actually a bit intellectually superficial.
Dawkins, of course, was - perhaps still is - one of the Four Horsemen of the New Atheism:
New Atheism - Wikipedia. These four have been responsible for a fair amount of the vitriol thrown in the face of religion in recent decades. Their new idea has been to mount a crusade, preaching and evangelising against religion. They even at one point went so far as to produce a video, with consciously religious overtones, designed to engage emotionally with people's natural sense of wonder about the natural world. I found it faintly nauseating. I can't recall what it was called. Your "crusaders" will be the ones that embrace the New Atheism approach.
The attitude of these New Atheists is the antithesis of that of Stephen Jay Gould's concept of Non-Overlapping Magisteria (NOMA). While NOMA has its critics, it seems to me a far more productive way to discuss the interface between science and religion.
Sociologically, I'm not sure whether the New Atheists are a product of the so-called "culture war" or among its architects, but it seems to me they have contributed to making it worse.
