> Laws like these are not criminal laws, and are not meant to be enforced if by that you mean policed. It's up to someone to file a lawsuit, if they think the law is on their side. Then a judge will have to rule whether or not the law applies in that particular case, and in doing so they may set a precedent which will influence how later cases will be judged.

This is one of the reasons that the "loser pays" approach to the cost of litigation used in much of the rest of world would not work well in the US. We use private civil lawsuits to enforce things that would be enforced by government agencies in much of the rest of the world, so it is important that individuals can bring lawsuits against much bigger, much better funded entities without having to worry about getting wiped out financially if they lose.
