So, A=B=C=D?I don't count "independents" as having actually "left the church", they just changed denominations.
The CofS and the religion of Scientology are two different things. A person can reject one without rejecting the other. Some reject the organization while still professing an allegiance to the subject itself. Some reject the organization, the subject, and the founder, as well.
Even further, there are different flavors of 'Scientologists'. Not all of them accept or agree upon all the tech of the religion, and some even adopt tech from non-Hubbard sources.
(For example, it's my personal belief that effective, workable tech in Hubbard Scientology ends at the upper limit of the lower Bridge. I believe it's at R6EW that Hubbard begins to introduce incidents to audit that are not of the pc's origination. It continues that way, all the way through OTVIII. Force feeding pc's incidents to audit is fundamentally unworkable, in my view.)
