I'd have fired her too. She might be an excellent poet.
She's actively hostile to the purpose of the magazine. What a nightmare submitting to her. She sounds like the type of editor who destroys budding talent instead of nurturing it.
I wouldn't censor anything by tone as editor.( what comes in ) and submissions
But i would censor Meta material related to purpose and submissions by the Editor. because that will function as censoring or silenting alternative views or styles.
