In Dawkin's defense, he did not call people delusional. He called the notion of god delusional. That's different. Those that take umbrage at this might check their own belief systems as to their sincerity. If people are devoted to a belief system, then no criticism of it should make any difference to them.

You don't have to agree with Dawkins but to play a victim role here is silly. A large majority of the world believes in a god(s) and those that state otherwise are in the minority.

However, atheists have good reason to think of a notion of god as delusional since a large majority of fundamentalists have taken over and imposed their views on others.

There are intelligent people who are religious but comparatively few who have the "grace"
to understand those who are not. Unfortunately, these threads have been a launching pad for attacks rather than an illuminating sharing of different ideas.

Both science and religion are open to criticism in a pluralistic democracy. The difference is that in science, criticism is built in to the process. In religion, it's "my way or the highway."
