I also read the American Rifleman article. Having bought and read "The Athena Project" when I needed an airplane read book, I do not care for Mr. Thor. I admire his ability to earn a living as a writer and wish him the best of continued success, but it will not come from any further purchases on my part. And given the opportunity to read any of his other books at no charge (I mostly read books from the library in hard copy or download), I will respectfully decline.
MHO, YMMV, etc.
