I sort of feel differently about stage names adopted for professional reasons (or names as a conscious identity choice made by bicultural adults for themselves), and names as a factor in parenting a bicultural child. But I'm obviously not in a position to judge fears vs. actual risk, except in that ghastly reading-gossip-mags-and-judging-celebrities-from-afar sense. (I admit that I have a few post-9/11 hot buttons, too, and they are slightly pushed by this, hence the discomfort and temporary suspension of non-judginess.)
