I don't know which country you're in, but in the UK each congregation is registered as a charity, and gains great financial benefits by being such.
In view of their privileged position, I wonder if at the PUBLIC meeting you were warned about being removed for "talking" to others, you would have a very good case to present to the Charities Commission regarding your humiliating and demeaning treatment just for talking to other attendees at a PUBLIC meeting.
Perhaps if you casually mention the words "charitable status", tax-exemption", and "Charities Commisioner", to elders who challenge you, it may get them to hurry to the toilet!!
