I can see where, if you just happen to be Jewish, worrying about the ethnicity of a babysitter seems discriminatory. But if you are in a religious household it takes on additional importance. Do you want a babysitter who does not understand kashruth, or who does not understand other ritual issues (perhaps it is a khag and lights cannot be turned on or off, for instance)? What on earth is wrong with looking first to babysitters who understand these issues and can be trusted to know when there are ritual issues and what might be required?
