And I'm not disputing that point (at least not here, anyway). It's true that it looks like I was disputing it earlier, but that's because I had misunderstood what you were getting at (which I agree was my fault). What I'm saying (now that I do understand your point) is that substantive due process doesn't seem to cover the rest of the bill of rights. It doesn't, in and of itself, mean that the state can't do what the first amendment prohibits the federal government from doing.
