Not because it frightens them but because it's irritating to have to sit through that dribble. Personally I want to get rid of all laws that were made because of religion. Like, no alcohol sales on Sunday.
So then, I should be able to pass a law that it's okay for adults to sleep with 12-year olds/minors, because this is based on religion. I should also be able to pass a law that adults can marry animals if they want, or have multiple wives/husbands. I can also pass a law that says if I need something and you have it, I can take it from you by force. If I don't want to live next door to someone with brown skin, I can kill them. If I find you annoying, I can kill you. If I lie in court and it's for my own benefit, it is excused and permitted. If I want to walk around naked in public, I can do so. If I want to peek into your daughter's window at night, no problem. If I want to sit in the park and masturbate while watching your kids play, that's fine.
You see, ALL of these laws are fundamentally based on religious morals. When we remove the religious foundation, we can justify and rationalize almost anything. You don't have any property rights, you don't have equality, what is good or bad for children isn't your business. **** you if you're offended by me, don't look! These things go out the window when we remove the religious moral foundations supporting them. That's what you are essentially arguing for.
