An addendum to the last post: that reference, and many more helpful pieces on the subject of Same-Sex marriage, are included in what I think is one of the best readers on the issue: Andrew Sullivan’s Same-Sex Marriage: Pro & Con. Its a helpful collection of some of the strongest arguments on the subject, and a helpful resource.
I’d commend it, particularly given the fact that it marshals strong arguments on both sides, the author admits his own bias and position, and it is fairly balanced. You might get something out of it…
