*nod* That was Murry's paradigm - that part of the point was to be open and educate those who didn't know - I seem to recall a joke about putting Gentiles and children on the same plane for the purpose. ;)

He always considered it especially important given the historical context of Judaism, the misinformation and persecution. Had a good pedigree, too - I remember him pointing out, during the course of the evening, "And now we open the door for the prophet Elijah, which we started doing in the middle ages, and has the nice side-effect of letting the neighbors see we aren't murdering any Christian babies in here."

Talking about it beyond the specific, though, is definitely a bit too broad. It's something that's really case-by-case, sadly based a lot on judgment and common sense, the former of which varies wildly and the latter of which is decidedly uncommon.
