I do have a problem with this statement:
The government cannot force you to follow laws that go against your fundamental religious belief.
I can see it now.
Your honor, I killed my daughter because she was dating an infidel. I was only following my religious beliefs. My family's honor was at risk.
As far as I know, there's only one major 'religion' in the world that 'preaches' that. There is no other set of religious principles anywhere that I know of that advocates murder (and please don't make reference to the Old Testament of the Bible to argue with me, okay?).
There are universal norms of behavior that most of our original laws were founded upon.
It has aleld in been used and upheld in court. Some where in Arizona I believe. A Muslim ran over his daughter and claimed it was an honor killing so she didn’t bring shame to the family.
