Nein, so etwas ließ' ich nicht hingehen, wenn man nicht, eben dieses loyal-literarischen Sinnes wegen, mich erdolcht hätte.

translates:

"No, I would not let such things pass through censorship, if I had not been stabbed to death exactly because of that literary loyalism."

In other words: the author was not really Kotzebue (who is being parodied as a loyalist), but yet another satirist for the liberal opposition.
