How interesting that Father Reese and a number of commentators focus on how Catholicism is presented as opposed to how the Church's members treat children versus how ministers and laity of other denominations do so.  I am writing of behavior other than the most obvious -- the sex abuse.

When one has a Protestant or other non-Catholic parent, one also has grandparents, aunts, uncles and cousins who are not Catholic.  One goes to weddings and funerals in churches of other denominations.  Differences are not confined to dinner table conversations, if any, or how Catholicism is presented.  How the kids are treated by the extended families and their friends and ministers can have an impact.
