Stupid things religious people say

[Sheldon]

Plain to see his subject is maths, and not English.

Not sure I follow

Lennox is a pretty well known religious apologist, so the fact he's a mathematician is usually floated by other apologists when they use him as an appeal to authority. If he said what that text states, then I was implying his English skills must be pretty sub par obviously. Sarcasm aside, a more likely reason is that this sort of oxymoron using the word atheism is in vogue to sell books, ever since Prof Dawkins "The God Delusion", though of course a belief can delusional, as all beliefs are the affirmation of a claim, unlike disbelief or the lack of a belief.
