Y'know, and I hate to bring this up, Denial, but have you actually read Watchmen? It's understandable if you haven't - it's long, and dense, and requires at least three readings to get the most out of. From what you're arguing, it seems very likely that your reading of the work has been at least superficial - I suggest another reading, if you want your questions answered and fears allayed. Really, what you're arguing against doesn't apply to the work in questions, and if you took the time to read it, you'd probably very soon see and understand exactly why.
