Because I don't want the government coming into my life and telling me what I can and cannot do
I'm glad you are bothered by the idea of a government telling you what to do but that's what they are supposed to do whether you like it or not. If you lived in earlier times, Beth Din would interfere with what you are allowed to do in your bedroom and in your kitchen.
I know it sucks, but the only rights people have are what the Creator gives them. It's His world, so He calls the shots.
