Well, I said "sound kind of crackpotty", not "are crackpots", about the reputable writers. My point (ish) is that I would really like it if the non-crackpot GA writers would try a lot harder not to sound like crackpots! It is a real issue. I've never seen writing in any other field of math which so frequently strays into sounding unhinged. (Referring mostly to Hestenes + the Cambridge group here.)
