Voltaire is something of an outlier there with his "FW: an abusive fright" take in pamphlets and memoirs and letters, with no indication he thinks Crown Prince Fritz did anything wrong when rebelling and trying to escape, and even he doesn't claim this was Fritz' opinion (though it's clearly Voltaire's).

Heh. Yeah, he's definitely the exception to the rule of "don't criticize one's parents," right? Voltaire is just about the only guy who is like "yeah, my dad sucked and you can suck rocks if you don't like it," so I guess it makes sense that he's totally okay with criticizing other people's parents and thinking that it's totally okay to try to rebel/escape.
