Joyous, there ARE bad apples in every lot, but when they clearly look like frum Jews, it is FAR, FAR worse. I cringe when I see a news report and there are frum-looking Jews on it, in case one of them may have committed a chillul Hashem (which is often the case, unfortunately).
I agree with Out-of-Towner (you said it very well), however I don’t feel that I or my family members should be dressing the way the Yeshivish crowd does. We dress properly, and I have no aspirations to look yeshivish. I want to look menschlech. I truly DO feel uncomfortable physically for someone who is dressed in a way that has to be making him shvitz inside.
