The best thing you can't say about Winston "I am strongly in favour of using poisoned gas against uncivilised tribes" Churchill is that he wasn't Hitler or Stalin or the more freedom-loving but less talented people. I think his cute quote about democracy is similar, it sounds insightful until you compare it with anything more serious.
Democracy relates to various implementations of it like "blogging" does to "Wordpress version X.Y", and to various modes of control like an email from a friend does to spam containing a virus. There is a grey area, too, plenty of emails from real friends with viruses attached by intermediate servers.
I'd say the best thing you can say about democracy is that it scares power shitless, even when it's hardly effective and comes from the guts of people more than adult and focused thought and organizing. Once we ever being implemented without anyone who doesn't want it to work being involved, we can talk benchmarks. As it is, it's like writing a program in C, then letting a bunch of cats walk over the keyboard, then compiling, and saying C sucks.
