You asked: "Can somebody please tell me which of acid/alkaline theories is the accepted belief system in the acid/alkaline support forum?"
I would think most people want the one that works. That is my personal accepted belief system. There are many ideas being shared in that forum. Pick and choose what works for you just as I have picked and chosen what works for me. I hope that is a better answer.
If however you are asking for another reason...I don't have any suggestions. Sorry if my earlier reply was too short and to the point.
