i remember a long time ago i was watching a talk show on tv
there was an Orthodox Yid and a goy talking to each other about Judaism.
it came to the topic of Tznius.
the goy was literally laughing at the idea that a womans upper arm and shoulder should be covered. he thought the Jew to be a complete fool.
the Yid tried to explain that the goy had lost his sensitivity to the physical beauty of a woman, by being immersed in an immoral culture all his life.
needless to say neither could convince the other.
