Yes but there is punishment if you dine a la carte in this group.
That's what distinguishes mainstream religions from cults. There is currently a Jew scientist claiming she doesn't believe in a god and that's perfectly consistent with Jewish beliefs (LOL). She won't be shunned, lose her job, family and housing. Nothing bad will happen to her. If a JW said they didn't believe in god, all of those things would happen.
Piercing used to be a fringe activity that got you labeled as 'bad association'. If you did it too much, you could lose privileges and even be reproofed for stumbling others.
I don't remember if I got my piercings after leaving the borg or not. I do remember knowing I was going to be regarded as a bad person for having them, and mine are tame.
