I think that might get me a bit warm, too. I think that I've been told that you can "affirm" instead of "swear" here in Texas if you just tell the judge/bailiff/whoever, presumably ahead of time. But then I don't know for a fact how oaths are done here, or if it varies by the court.
The government shouldn't automatically foist god on all jurors, witnesses and defendants.
Precisely.
And the New Testament has some verse prohibiting swearing oaths anyway - "let your yea be yea and your nay be nay" or some such. So the Christians shouldn't be forced to break their own rules, either.
