I'm asking you to be put in basically the same situation, not an opposite one. The biggest difference is I'm asking for your permission.
My argument was never that Antoinette deserves some special privacy, so changing the subject of the act is not a strawman. Why should people enjoy someone else's private correspondence but not yours?
So you're fine with your private correspondence being public long after your death. Does it matter that von Fersen clearly wasnt? He knew his letters would be public and purposely blacked out parts.
