Crackpot really has connotations like "flat earther" and "aliens built the pyramids". It's one thing to say "I believe GA proponents' claims regarding the usefulness of the geometric product are overstated". It's another to say "GA proponents are crackpots".

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.)
