“How many books did Flannery OConnor sell?
How many books did Ayn Rand sell?
Let the consumer judge which is a better messenger.
I am not sure that Quantity of book sales should be a strict metric. One could always reply with: How many Korans have been sold? or: How many Bibles have been sold?”
Are YOU Flannery O’Connor?
I have no idea what this question even means.
