It's also not a true democracy because individuals don't vote on all measures. Instead, we elect representatives who do the voting for us, typically in line with, or in a more educated fashion than, we would on our own (well, at least that's what my social studies teacher said back in the day). I don't think there are any major countries which are true direct democracies although if you like the idea see the Demarchists in Alastair Reynolds science fiction. Everybody votes on everything.
