but there are plenty of sources of information about evolution you can suggest whose author hasn't called all religious people delusional.

So are you saying that a person who says that believers are delusional (which, as all rational people know, they are) couldn't be a reliable source of information about evolution? Good heavens, Wacko, darling, you are not only delusional, you are also irrational. Do entertain us by trying to defend the above statement. No rush.
