This sounds extremely concerning if correct. I can grasp what "inquiries" consist of, but "plain persecution" has me baffled. Can you provide an example of such "persecution"? I am not being facetious in my request.
I'm not sure if it's "persecution" per se, but there have been a number in halls in that area whose views and beliefs on partaking are "known" to the elders there. They've consisted of long serving CoBE, regular convention speakers, those who have professed being anointed for decades (even when they were in positions of significance in Bethel), among others. Most have been smart and played the game well because they actually know the rules, so they haven't been DF'd.
One of them who was DF'd is now one of the key writers on anointedjw.org. I thought I saw his first-hand account of his JC posted here a while back, but maybe not. I can definitely confirm that there are others who agree with their logic, but would never publicly join them. Definitely a known issue in the area, though.
