What about disfellowshipped people? I couldn't wear badges for the three conventions I went to as a DF'd person. But if you didn't go then the JC elders would hold that against you.
Because I was DF'd and didn't have a parking pass I was questioned about paying one year. I had a medical directive in my wallet and used that - there was no way in hell I was going to pay for parking to go to a convention by myself and be treated like Little Miss Invisible for three days!
