History shows that the real mass murderers are always governments.
RJ Rummel of the University of Hawaii wrote a book called "Death by Government". In it he cites evidence of as many as 300 million people murdered by governments over the course of history. That's MURDERED, not killed as a consequence of wars or legally killed for committing a heinous crime.
By some counts, there have been 10 billion humans since whenever you conceive history to have started. If true, that means that three percent of everyone who has ever lived was murdered by government. Three out of every one hundred.
Governments are the only organizations with the resources, the ability, and most of all the "authority" to commit murders on a mass scale. Even the Mafia or drug cartels can't kill that many people, and couldn't do it and get away with it. But liberals think we're all nut cases for fearing an out of control government.
