This demonstrates my earlier point, that some believe that to reject the WTS means they have to act opposite to everything the WTS said.
It's basic set theory - they have lots of do's and don'ts, some of them are invented but others overlap with general society. Cheating on your wife, killing people, stealing money - these are all widely recognized bad and "immoral" things, and don't make you a JW or WTS adherent. Likewise, you don't have to do any of these things to demonstrate how non-JW you are when you leave.
You can be a good, decent, honest, loyal person when you leave the WTS. The people who claim you cannot, that it's some unreachable level of perfection (e.g. suggesting someone who doesn't visit prostitutes has "saintly mastery of their penis"), are simply bad people.
