The original French libretto isn't his work and is pretty Jacobin though (ie, not only pro-Revolution, but pro-regicide and recognizant of the necessity of the Terror and even of Robespierre's opposition to the war and his role in the abolition of slavery, so I don't feel particularly bad about liking it. Especially since the librettist wrote it for the bicentennial of the Revolution - though that didn't work out - and had no idea about the circumstances of its premiere (having died in 2004).

As for the issue of supporting Waters by paying for it--well, I've already done that, unfortunately, and ceasing to listen to it or selling it or breaking it wouldn't change that.

(But I completely understand your feelings about the putridness of class systems, and of England's especially. I share them--and feel that fox-hunting is barbaric.)
