LLW, you mean we should just be good Jews at heart and dress however we want? We just need to act nice to goyim and all is right ? Absolutely not. That is not what Yiddishkeit is all about. That is why women dress so pritzusdig these days because they are given the green light to do so.
We are supposed to dress and act b’tznius because this is what Hashem asks of us, not according to how goyim percieve us. Btw, dressing goyish and pritzusdig causes Hashem’s anger and He withholds his protection from goyim’s hatred. I see a correlation between the recent upscale in anti-Semitic incidents in the US and the way frum women AND men dress, trying to blend in with the goyim by hiding their Jewishness. If we don’t shape up it will spin out of control. The Holocaust started in Germany because so many sought to “show the goyim” that they are proper German citizens and it blew up in their faces. We don’t have to “show” anyone anything. We need to live as Jews and be tzniusdig with our dress and actions.
