Interesting stats. I have a family member that lives in the world of religion, divinity, higher education and PhD's, so I was mostly aware of his flapping about all things Tolkien and C.S. Lewis. So reading your work shows the bigger picture of religion's claims to these writers.
I am not quite sure if I say congratulations and I am happy for your "big splash" on this topic, because I would assume that the furious feedback would not be the best thing ever. I guess it depends on your perspective.
If there were awards for such accomplishments in writing, you would have them. It's exciting that your work is getting so much attention. Applauding your successes!
