Words I can’t use to describe the Army and their supporters in 1648, because these political terms weren’t invented until much later: radical, extremist, republican, revolutionary.
What the hell am I supposed to call them, except “those guys with the sentiments that freaked the shit out of many seventeenth-century English but look pretty familiar to those of us living in modern democracies”?
(And that’s a whole separate problem — figuring out how to present Antony’s feelings on the Levellers and their ilk, when many of the things the Levellers stood for are the conservative end of ideals we cherish dearly today. The easy solution would be to make him a sympathizer to their cause, but that’s what we call an author cheesing out on historical accuracy. Most people at the time thought the Levellers were trying to destroy the fabric of society. So: find ways to say Antony thinks democracy is a bad idea, without making readers dislike him for it. Somehow.)
