Reply To: Tznius in front of Non Jews

the reason i brought up “non Jews” vs. Jews is because there seems to be a distinction between the two in terms of Kol Isha- i heard from reliable source that there is not issur for a jewish women to sing in front of a non jew because issur of Erva is only for a jewish man.

i was wondering if there was a halacha that i myself was not familiar with that perhaps was an extension of the concept that Erva not an issue with a a goy, that gave the heter for women to attend exercise classes, where they wear pants, and have other males attend the class as well.

I also gave the example with the production, because many of the workers who work the lights and sound are not doing that the entire time, only at certain segments of the show, the rest of time tehy are watching the girls act/dance/sing…so I though perhaps there was a leinency that i was not familiar with?

Someone brought up the question of how one verify that the males were non jews- that is why my original question included the example of african americans attending the class( and for those who converted, they are not attending exercise classes with women)…
