Sure.
And a lot of the "cure" stuff IS NOT Universal.
I Think PohsFriend said -- One Size Fits One -- or something like that.
What I learned as Mrs. Hammer's Master of Science for Social Work study buddy -- in Social Work Therapy stuff -- any particular cure that hits 33% is Very Successful. So you need a menu of various "cures" that fit the wide variability that we humans are.
One thing I have found is that folks' who claim THE ONLY WAY or in converse THAT OTHER WAY TOTALLY SUCKS . . . . usually are not too well informed about that which they speak.
Even if AA hit 33% (I think the typical numbers are a little less than that, dunno), and AVRT/RR hit 33% (dunno what their claims are), you would still need a whole other method/approach to deal with remaining 34%.
The entire I AM RIGHT -- THEREFORE EVERYONE ELSE IS WRONG routine is what tends alienate so many from religion to start with.
