When my jw joined up he was not told about all the rules.
Nonsense. Before baptism jws are required to go through three separate one hour (or more) sessions answering around 300 questions that deal with every aspect of jw life including the obligation to shun. Its sad and frankly awful but no one can claim they didnt know. Also no one can get baptized in a short period of time (one or two months) and then claim they didnt know. You have to study for months (sometimes years) then go out in field service consistently (sometimes a year or more) before you can be considered to go over the questions for baptism.
Maybe he had buyers remorse. Maybe he was just really bamboozled (lots of us were) but to say he didnt know? Dosent add up.
As for the OP... have fun titling at that windmill. If a petition makes you feel better then petition away.
