So what you're saying is that your neighbor must be wrong on everything, and conversely, you have the right to lord it over him because your right? Does he believe global warming (let's stick with the original premise that has become inconvenient to stick with because the facts don't back it up) is incorrect, or does he think that the climate indeed does change, but that man isn't the principle cause of such change? It's a complex argument. As far as the water on the lawn, I'll bet you everything that both of us own that the water that comes out of your faucet is vastly different than the water that was pulled from the reservoir. Chlorine may not be good for lawns, fluoride may not be either. I don't know, I don't have public water. Your supposed point here is non-existent. It would be like me, as an atheist, saying that anyone who believes in God can't be right about anything else. And I can't even say for sure whether they're right about God. Their guess is as good as mine.
