Dear all -- Thank you for the replies. My question was asked in good faith. Nobody who has actual experiences with the issues I'm talking about would approach them lightly. I said less rather than more in my post because this topic seems to me to require particular discretion and because I realize some might consider the entire concept that I've raised to be objectionable. But I've had a couple of good private exchanges as a result, and am grateful for them (and for any to come).
