Could you explain or discribe JW "different forms"
Well Deputy, correct me when I'm wrong but it's my impression that the organisation more rapidly turns a blind eye to divergent clothing, entertainment or other leisure activities (of course within the strict scriptural boundaries) than to alternative doctrinal views. Apostacy, then, remains the most deadly sin in the eyes of the average JW.
Uniformity always makes me think of uniforms, a strict dress code, like in a monastery or a boarding school. I believe that's not the case for JWs.
