For them dual identification is all but unavoidable, and by now most Jews and Buddhists (except the most conservative) seem to accept this. Is it so strange, then, for gentiles to dual identify as well? After all, you can't just renounce your family, culture, or upbringing. Of course there are points which are difficult to reconcile (just as there are within each tradition), and again, conservative voices will predicably oppose everything. I would say that the goal is not a "pure" religious practice, but an authentic, practical one--which admittedly may prove challenging for the group identities of other people, but that's globalization for you.
Being Jewish is as much an ethnicity as it is a religion. You can be Jewish and Buddhist in the same way that you can be Italian-American and Buddhist.
Sure, you can take a cafeteria approach to Christianity and Buddhism and call yourself both things. But Christianity revolves around an omnipotent, personal, creator god and Buddhism says believing in such a thing is a harmful wrong view, so there is a big conflict there.
