"Sure, nonsmoking restaurants could exist now, but your strategy is to post it on their door whether or not they're smoking. Most families would not bother to know the establishments that allow smoking"

I could have said the same thing about bargoers and bars that have a waiver. You ignored my point about the majority finding this acceptable. Perhaps your facism is starting to show.
