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.
