Atheists can't call theists "delusional" because atheists don't actually exist. They aren't real, and Richard Dawkins is a fairy tale. Dawkins was made up by his disciples and he never wrote the book The God Delusion. It doesn't exist either.
And you know how I know it doesn't exist? Because some really stupid books exist! How can Dawkins' book be real, when all these ridiculous books exist!
So tell me, if Dawkins' book actually existed, how could it have been printed? Everybody knows that books explode into existence from a singularity when they decide the time is right, they're not designed and printed! What a delusional idea!
And not only that, some people that have written books have done terrible things! Some murderers have written books! Hitler wrote a book!
That means that anybody that writes books is evil! Don't you see how this proves that The God Delusion isn't real? The disciples of Dawkins made the whole story up!
And look at all the different kinds of books that exist! Some of them even contradict each other! How can atheists be real if people that write books can't even agree on anything?
Are you beginning to see the problem here?
Atheists love to point out how many "religions" there are. But "religion" is a separate question from whether or not the universe is designed and created.
Some silly views of god(s) exist. If atheists can point out how silly some are, this is not evidence that the universe was not created by design. It is a separate subject.
We hear that "extraordinary claims demand extraordinary evidence." Well guess what. A pre-big bang singularity is an extraordinary claim. The idea that the universe was designed and created with a purpose, by an intelligence is no less extraordinary.
Atheists will point to evil things people who claim to follow one god or another have done. Though it's a demonstrable historical fact that pagans have killed many times more people, they still point to all these evils as if this were evidence that no god exists.
Excuse me? Aren't these completely separate questions? None of this is evidence that it's an unreasonable conclusion that the universe may have been created for a reason, by an intelligence.
You can disagree with this conclusion, but atheists have failed to show that it's an unreasonable one, let alone a "delusional" one.
Most outspoken atheists are well aware of logical fallacies. Yet they repeatedly commit this one. It doesn't matter how many different views of God there are. It doesn't matter how badly some people behave. This is not evidence that theist conclusions aren't reasonable.
In fact, if there is a Designer/Creator of the universe, it would not and could not happen any other way than that human views of a god vary widely, since such an entity would be superior to us more than we are to ants.
I'm not asking atheists to see what I call evidence as I see it. Their opinion is their opinion and they have a right to it.
What I AM saying is, that atheists have not earned the right to call the views of theists "delusional" any more than theists have earned the right to call theirs delusional.
