The problem with that is what do you consider a faith-based law. Several of the 10 commandments are part of US law (and most of Europe as well) Does this means that laws prohibiting murder, theft, and purgery should be disrespected as much as a law requiring belief in the Jedeo-Christian God and prohibiting doing business on Sunday?
I think a line can vaguely be drawn at - When a law is based on some moral preventing an action that does not infringe on anyone's rights and harms no one. The only one that comes to mind is same sex marriage bans. I am sure others can fill in more.
! Is the wink indicating a joke or have we forgotten that with or without the ten commandments, murder and theft are wrong?
