We've been over this before, but that isn't a Thomas Jefferson quote. It's from a 1914 debate against socialism delivered by John Basil Barnhill that over the years has been misattributed to a bunch of people like Thomas Paine and Thomas Jefferson.

He's claiming that John P. Holdren's book, EcoScience, discusses diet injections and injunctions to control the public. And I really honestly think this is a result of him never reading the things he rants about reading all the time. When he's talking about isn't a reference to eco-science, the textbook that John P. Holdren wrote. That's a line that Alex always misuses from Bertrand Russell in his book, The Impact of Science on Society.
