My question is: If it's so terrible to remove your chalat, not your shirt, c"v, but a thin robe, then why make fun of yourselves and go into the water like that? just stay out! I'm sorry if I sound all "enlightened" to you, but this looks like the Iranian Women's Soccer Team, nothing less. I'm sure to 98% of frum Jews it does too. The boys look happy. I guess.
Where does this extreme behavior come from? When I was a young bachur in camp, Chassidishe camp, there was maybe one bachur who never removed his hat and chalatel. And gartel for that matter. This one was a Belzer chossid, and Belzers are known to always wear hats and gartlech, and I give them all the credit in the world for having the intestinal fortitude to do that, especially in the blazing heat in Eretz Yisroel. Needless to say a bachur like that wouldn't go swimming, that would involve taking his gartel off. Although now that I see that there's the above option I wonder why HE didn't go swimming like that... Back then I never dreamed that it was widespread like this, but you live and learn. I just wonder why groups like that don't give their adherents the benefit of the doubt when it comes to what the rest of the world considers NORMAL behavior; why they think a bachur can't go swimming without crazy thoughts going through his mind????
