Is God a logical contradiction?

[Belacqua]

And, of course, you had to find something that's not in the David Bentley Hart's book

This is all in The Dream Child's Progress and Other Essays by David Bentley Hart.

And he does makes attacks on Dawkin's, Hitchens, and some other personas instead of what they said/ wrote.

He calls them some names because he has found so many errors in their books. But an insult is not an ad hominem attack. An ad hominem attack would be something like: this person is a Christian therefore he can't think straight. 

If you point out a couple of dozen errors and then say that the person makes a lot of errors, that's not an ad hominem. 

Did you look at the Wikipedia page?
