DY, I’m not a fan of PETA 🙂 I think they do a lot of crazy things. I do think they are the type of people to paint of the streimel of a chossid.
But I do think its important to live by the rules of the land, when halachically feasible. In this case it was and given H&M’s own writings for marketing, they would have modified the ad had someone contacted them.
These bochurim covered parts which we can agree are NOT erva (like faces).
I didn’t support throwing acid on women who weren’t dressed properly in Israel either. There are better ways to handle this situation and IME in today’s day and age the zealousness doesn’t often come from Torah.
