We really are on two different paths here. The original subject was air quality in China, and I mentioned that the federal government is going to relax regulations on mercury pollution, which, as we both know, causes great harm to humans. I've been around the block a few times too, and I realize that we will always have "radicals," like them or not, and they provide balance on issues and bring into focus forward-thinking ideas, which expands our own focus. I'm not radical, but I appreciate the role that they play, and I believe in sensible compromises. Answering your question, "Where does it stop?", it doesn't. There is always room for improvement. If stopping was the right thing to do, then we might be still throwing human waste out the windows and onto the streets. I know, that sounds completely unthinkable for us at this time, but I'm sure in Medieval times everyone thought it was an okay thing to do and anything else was too radical.
