No, I am NOT in favor of the vernacular. You TOTALLY misunderstood the point I was trying to make (apparently not too well, however). I am opposed to the use of anything other than actual L”K for Jewish names. My point, very simply, is that if you believe Yiddish is appropriate for naming a Jewish child (because the Jews of Europe spoke it and it was a single unifying language among them, and used for disseminating Torah in great numbers and yadayadayada), then you should have no difficulty whatever in using ENGLISH for the Jewish names of Jewish children, as English is now the number one unifying language in this country, and more Torah than ever before is being taught in ENGLISH.
I do not believe that either Yiddish OR English is appropriate for naming a Jewish child, ONLY L”K is truly Jewish. Yiddish was appropriate for its time strictly for communication among Jews of various Eastern (but not Western) Jewish communities. IMO (to which I have a right), neither Yiddish nor English is really that appropriate for naming a child in them, and certainly one language is no “holier” (anymore) than another, based solely on what I expressed about the language used for learning Torah.
If you are objective and forget your nostalgic feelings for the Alte Heim of the past, for the moment, you will understand that English has already replaced Yiddish as common communications ground among Jews in this vast country of ours, not to mention many other countries. Except for chassidim, I do not know any Jews in my peer group who speak Yiddish, though all speak Hebrew, which IS our language.
To sum it up: Yiddish/English names out, Hebrew in.
