> It may be common, but it is not normal.

Those words are synonyms. What you seem to be objecting to is that it should not be normal or common. But it is. “Normal” doesn’t mean “acceptable” or “neutral”, it means “standard”, “usual”, “typical”, “expected”, “common”. Slavery was never ethical or good, but at a point in history it was normal.

Don’t avoid what is in front of you. Do fight for a better normal but recognise when something you disapprove of is the current normal.
