I have read it, and it has all the hall marks of the religious right... now if it was intended or not is another matter. It is after an old law, and back then there was no "religous right" as we know of it today. But society was very different and did not see anything wrong in putting such stupid laws on the books. That does not mean we today should agree with them or even have them on the books.
But the fact remains that states in the US and even in European countries, still have laws on adultary and other so called "sexual crimes".. for example consentual sodomy. That most countries or areas dont inforce such laws, does not mean that they are not valid still and if there is a religious wack job that gets elected, then you bet that these laws will be inforced. These laws and ideas are outdated and belong in the dark ages when the Church had massive power over the people and political establishment. The legislative in any country that has such laws on the books, have to start to earn thier pay by elimiating such idiotic things.
That I single out the US in this case, is because this article was about the US, and the US is way more religious in its laws that Europe is on average, but I dont deny that Europe most likely has similar outdated idiotic laws on the books somewhere.
Now the biggest problem is movements in the US, but also all over the world, trying to put religious doctrine into law, so that all have to follow it. As I said, I read that in Virginia, that the religious right wants to put restrictions on divorce and that only the beginining I bet.. but thats not saying they will get thier way of course.
Now to put it in perspective, Ireland and Poland on abortion, Poland and attempting to force Christianity in as the offical religion of the EU, the fight in Europe against registered partnerships for homosexuals (which the religious freaks thankfully lost) and other things that religious circles are putting pressures on politicans to force through on law.
Religion has nothing to do with politics, so stay out of it. Religion kept humanity dumb and blind for almost 2000 years, enough is enough.
