Moderation in large part *must be about the bias towards protecting vulnerable people. Vulnerable people by definition are more likely to be targeted AND have less power, meaning moderation is serving a protective function against dominance. This will always be subjective, but there's almost certainly evidence in abundance that some kinds of people, typically with less cultural status, are more targeted and more at risk of harm by being targeted.
Even if you take this perspective, different groups are considered vulnerable in different parts of the world and it seems the API uses the American perspective. E.g. Scandinavians are a less protected group than Italians according to the article. But if you are in Italy, you will likely find Italians to be less vulnerable. Even if you agree with the rankings, this just means you come from the same cultural perspective and others will disagree.
This is a fundamental problem with identifying hate / bias and I think its important to understand our current limitations.
