Most of you are saying a similar idea (symbolic of general desire for torah lifestyle), which I would guess would be R' Wallerstein's actual answer. A few responses were strange at best - see below. I suppose my befuddlement is that it seems like a very surface level kind of at thing that sort of hints at lifestyle issues, which would be strange to make a symbol out of. But obviously this is not my field, and I can hear where maybe he would say the metzius is that the additional piercings are in fact very symbolic for these girls, and therefore for him when they agree to remove them.
in the Torah, only a slave gets piercings...
Source? It's a nice shtikel torah, but I think most Jewish women have the 1 piercing on each ear, and many major poskim explain why that's mutar. Any halachic issues with further piercings are related to issurim of chavala, chukos hagoyim, maybe even kedoshim tiyu depending on the location - not because of some explicit issue of being like a slave.
Imagine it’s your child chv”s.
Not sure what this means exactly. If ch"v my child was OTD with all sorts of piercing, and they were chozer b'tshuva, would I hold onto their old piercings, or would I specifically want the person who was mekarev them to hold onto them? Hard for me to answer without being in that situation, but I would imagine the answer is no.
many of these piercing's where also in not very aidel places
I would imagine that would make me less likely to pin them to my tallis bag, not more likely. Do you specifically know that's what these were?
