I do not want to pin a scarlet "A" on the breast of every man or woman who has sinned. I want something much more modest. I want people who commit this moral trespass to have the decency not to attempt to profit from it in the national media.
Here's what I'm guessing: We have some of the tools right now to stop it, if we wanted to use them. Some of the men hooking up through Web sites that advertise adultery probably live in states where adultery is still technically against the law, or where torts of criminal conversation or alienation of affection exist. An injured spouse or an aggressive state attorney general could make a case out of this.
But we could also update these older torts of adultery with new language that makes explicit that commercial enterprises that intentionally and explicitly attempt to profit from acts of adultery expose themselves to lawsuits by the injured wife and children. For that matter, why isn't commercially soliciting for adultery as much of a crime as soliciting for prostitution?
People do bad things. We can't always stop them. But we could prevent them from turning adultery into a business model.
