I’ll add one more thought, to put the concept of piercing in perspective:
A few years back, R’Amnon Yitzchok had a crown for a sefer torah fashioned from asst piercing jewelery that chozrim b’teshuva handed over when they were ready to begin road back to observant Yiddishkeit.
He asked for these to be handed over, as he saw this as the first step in putting a distance between the street culture and ours. By doing so, the person made a clear and unequivocal statement of who’s team he was now on.
So I ask you, if you see a bas yisroel with a piercing thru anything other than her earlobe, what do you think she is trying to tell you?
