don't know the guy, but he seems quite eminent. my only comment is well, yes, but there's a little bit more to being sephardic than rationalism. i mean, there's a big picture of spinoza, a big picture of derrida (!) - no rambam, ramban, etc.... it kind of misses the whole thing about sephardic mysticism, poetry, song, to say nothing of halakhah. i mean, if you're going to consider everyone non-ashkenazi as sephardic, from morocco to yemen to afghanistan, that's kind of like saying that the only thing to ashkenaz is einstein and the vilna gaon, which would be ridiculous - and how rationalist is ovadia yosef? what price shabbetai tzvi? basically, it's a false dichotomy which reflects more about the writer's interests than anything else.
on the other hand, there was a link through to this amazing site with piyyutim - music and lyrics, too, which will really help me out, so ta very much for that anyway.
b'shalom
