That's not how it works, and this is fundamentally different. In the US, the offended person would have to sue the offender for libel or defamation. The State would not be bringing charges because this is not a criminal matter; it is a civil matter. Nor is it so obviously defamation or libel, as you suggest. The lese majeste law is not a matter of the King suing the offender. It is a matter of the Dutch state pursuing criminal prosecution.
