There are also many definitions of god, and Dawkins engages with all of them. Dawkins is much more strongly opposed do theism, than deism for example. He engages with philosophical ideas about god.

Dawkins argues that we don’t need god to explain the universe, life, or anything else. He further goes on to argue that religious belief in god trains people to be irrational fanatics, which damages society, progress, science. In the end Dawkins says, there’s no proof for the existence of god, and that we would all be better off without religion. However IIRC Dawkins recognizes that religious belief can have positive psychological effects.

The new atheists have become their own subculture with its own values. The online new atheist scene also attracts people who love to argue, provoke, and pick fights. Contrarians and skeptics are not the same, but can overlap.

There‘s also a pipeline that goes like this: new atheism > anti religion > anti islam > white nationalism

The issue here is that the left has abandoned its opposition to religion, especially regarding Islam, in the name of anti-racism and intersectional identity politics. So these people are rejected by the left and driven to the right.
