Hedonism at its worst

Here's an article on polyamorous relationships. Basically, it means that each spouse's "piece on the side" is considered a part of the family. Now, I know there are some who will say "if they love each other, who cares?" but if children are involved, I think this is just plain wrong.

You just don't raise kids in this kind of environment. How are they going to grow up with a healthy sense of the way relationships function if people are dropping in for a little action whenever the mood moves them?
