The always-menshlich (and I'm not being sarcastic) Brooklyn Wolf posts on the hypothetical question of whether he'd save a Gentile's life on Shabbat (he would, as I knew he would). The comments are interesting--Brooklyn (I take the liberty of using his first name) has more hareidi commenters than I do. He also has more nonhareidi commenters.
I posted on a similarish theme some time ago.
