Most of the people I know who are against same-sex marriage are just like my parents: elderly, religious, set in their ways. Fortunately, their old age means that they'll be dead and gone in a decade or two. In the meantime, the best we can do is to inoculate our children from such bigotry.
Like many other parents our age, we've made it a point to be socially progressive in the upbringing of our kids. When gay marriage became legal in New York, my wife brought home the front page of a newspaper to show our daughter that two girls can marry each other (and one day you'll see two Disney princesses fall in love with each other, we hope).
But why stop there? How about other people's children?

Can you guess which "educational book" we'll be donating to the Christmas Giving Tree this year?
