A group of Jws breaking off and forming a sect would have little impact on the WT Society as a whole.
What needs to happen is the sect needs to be formed among card holding JWs themselves. If IT was possible for Ray Franz to get a following inside the WT society so a large number of JWs would follow his opinions this would have the effect of forcing the WT society to accomodate their opinions or be faced with a large split in the JW religion.
This is precicely how other churches work and is a good thing because it keeps everyone honest and tolerant of others. In the SDAs my own church there are traditional Adventists , Evengelical Adventists , Liberals just to name a few and all are accepted .
The WT society will eventially evolve into a more reasonable institution.
