Hi Wind_rider
You wrote "..my theory that it's a bunch of people who actually have rheumatoid (or God knows what else autoimmune problems or infections) gumming up the diet results ....". This fits nicely with what I have written to John above - the Low-Kleb AS who have "God knows what else autoimmune problems or infections".
You seem to suggest that questioning the application of the diet to any AS weakens the case for LSD / NSD , offers an excuse for those looking for one and encourages more use of NSAID. That may perhaps be so but it should not stop us searching for the truth. If there are people diagnosed with AS who genuinely do not respond to diet we should admit it regardless of the consequences.
You said “There is an exception for every criteria.” I think that the Low-Kleb AS may be that exception among the general AS population.
