You would consider that decision politically neutral?
(for the record I do realize the phrase 'politically neutral' is vague and unclear, and often used as a conservative dogwhistle, which is why I generally avoid it)
An example of the sort of Code of Conduct I personally feel is the most inclusive and 'politically neutral' in a non-scare-quotes-dogwhistle way is the Hacker News guidelines[0]. I think the moderation in general here does a good job of promoting open discussion across people from a wide variety of backgrounds.
