Menachem, i disagree. Being moser nefesh for one’s country in itself isn’t heroic or praiseworthy. If a black man sacrifices for klal yisroel because he thinks he’s Jewish(like kanye west, black hebrews), is he sacrificing for the real klal yisroel, or just to his fake contrived fairy tale?
Same with a totally frei jew – they have absolutely no idea what a Jew is; to them it’s no different than an italian, or spanish person championing spanish and italian causes.
