The word “democracy” has a colloquial meaning that is used in common speech. In the U.S. we have a “democracy” as that term is used by most people. You sound like the people who say communism has never been tried.
I'd say he's illustrating the nuance intended by people who say communism has never been tried. On paper, both democracy and communism have been tried. In reality, both have been ham-strung by human greed, corruption, propaganda and good-old apathy.
In an academic setting where people are using precise terminology these nuances are worth debating and are important. But in a forum such as this one where it is clear what one means by “democracies” this is not appropriate. Clearly there is a distinction between Russia/China and the U.S./most of Europe in terms of freedom/elected representation where one side is called “democratic” and the other authoritarian. Pedantically quibbling over precise definitions is useless in this context.
Talk about straw man!
