Allow me to offer a differing opinion to the last couple of posts.
Should laws be interpreted, or even written, with religion in mind? Well, I believe in the separation of church and state. What that means is that the ruling body of the government should not be tied to the ruling body of the church. However, what that does not mean is that the ruling body of the government should set aside their religious beliefs when doing their job as public officials.
The Constitution of the United States provides for the governing body of the country to be composed of appointed and elected officials. In addition, in all cases where there is an appointed official, there is ultimately an elected official whose job it is to appoint someone to that position. In theory, they will find someone with the same values and/or agendas that they have.
If such an appointed or elected official has a religious standpoint and wishes to express that view, then there is nothing wrong with this. In fact, I admire such people for standing up for what they believe in under the circumstances.
Why is this okay? Because the system is built with checks and balances. The people of this country (speaking of the US since we are currently addressing the US Pledge of Allegiance) have the right and duty to elect the people into public office that they feel best represent their own personal values and beliefs.
If an elected official has religious beliefs and chooses to let those influence how he behaves in office, so be it. There is nothing unconstitutional about that. If that person has been true to those values throughout the election process, then there should be no surprise that they feel that way once they are in office. If the nation doesn't approve of that sort of behavior, then the nation will simply elect someone who doesn't behave that way.
Granted, the system is not infallible. But for the most part, it works well enough.
Concerning the pledge of allegiance, no one is forced to give the pledge. People argue that their right to freedom of religion has been violated because they are forced to listen to it. These people would instead suppress not only the freedom of religion of those who do want to pledge their allegiance with those words, but also their freedom of speech.
I've seen too many cases of people trying to hide behind the constitution to try to get their way when their rights haven't been violated in the first place. The last thing I want to see in this country is a situation where an individual can stand up and get their way by complaining that they have been offended by what everyone else wants. That's why we vote, people...
I'll grant that there are times when special attention should be paid to the minority. For example, slavery was never appropriate and shouldn't have existed based on any claim, including the fact that the slaves are a minority and we've decided as a group it should be that way...
But when the country as a whole is told how to behave to avoid offending the minority... When we worry more about offending the minority than the majority... Then we have gone too far.
