SJSinNYC, do u think it looks stupid to wear a skirt instead of shorts in 90 degree weather, well to some pple it may look stupid. Or how about pple that wear knee socks/tights only instead of anklets, does that look stupid? U have to be proud that u are a jew and not worry about “looking stupid”.
When there is nothing halachic involved, yes I do think its stupid to add an extra jacket to make you sweat more. At least a hat you could argue is protection from the sun or something…there is a big difference between making sure you are following halacha and following a uniform. So yes, in my opinion, wearing a jacket in 90 degree weather is stupid. If thats what they need to be frum, then great, but its not halachic in nature so its nothing that I am going to look at someone and say “Oh, I respect them for ensuring that they are being stringent in halcha.” I would say that about someone who wore tights in the summer even though its hot because to them its halacha. Do you understand the difference?
And I am proud to be Jewish, but it doesnt mean I have to be proud of non-halachic things other people do.
