"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof..."
Take a good look. Seems pretty simple, doesn't it? Then explain to me why we're once again having to deal with a case of someone being offended and thinking that this clause gives them the right to sue to have the offensive historical object removed. As the Ten Commandments are a part of this nations heritage there is no 'establishment' by their display. Congress has not passed a resolution forcing everyone to convert to Pentecostal or Baptist.
So why did the Supreme Court have to review not one but two seperate cases about displaying the Ten Commandments on government property? Because there are some people out there who just cannot stand to have anything that disagrees with their narrow view of the world on public display. It offends them to see the Ten Commandments so the Ten Commandments must go. It's this mentality that is causing so many issues in this country anymore.
Where does it say in the US Constitution that you are promised a life free of ever being offended? Where does it say that you will be able to impose your views on others to avoid being offended? Make no mistake, the people who are so 'sensitive' that they can't handle the mere sight of something like the Ten Commandments are doing just that. They want to be able to go through the day happy and carefree and not have to confront anything like this. If they have to trample on some other people and their rights along the way they have no problem with that as long as they get what they want in the end.
