Hey, I thought we had a rule from way back about not using the dictionary! (I know I always get crap when I do it.)
Anyway, you do make a point. Allow me to re-phrase my complaint.
When the "diversity" of thought among the Protestant sects is brought up by Catholics (usually to make a point about the chaos of individual interpretation), Protestants usually rally 'round the idea of the diversity in thought and worship being insignificant, or in "non-essential" areas.
When the idea of ecumenically trying to address and smooth out these very same "insignificant" and "non-essential" items of Protestant theology, all of a sudden the very same people become convinced of the absolute rightness of every facet of their personal belief.
I found it ironic, excuse me if my previous pithy statement didn't explain adequately.
