"No offense" but isn't this the second time you have posted in a manner as to insult people here under the 'guise of just trying to find out more information about Witnesses? If you truly want to find out why so many people have such strong feelings about not being a Witness anymore then I suggest actually doing an academic study about the religion by reading a few books that study the doctrines & traditions about Witnesses...but don't post about people sounding paranoid and then try to say "no offense". It is insulting to call someone even borderline paranoid if you haven't ever been in their situation and haven't taken enough steps to even understand what they are going through...
On topic now...I do agree that some are overly anxious about posting here. However, I do remember more then a few posters saying how people have reported them to elders & family members for finding out that they posted here. When you have so much to lose (association with family members & friends, the loss of your reputation) then it is understandable that you might be skittish about even perusing a message board like this.
