> So I asked dozens of Bosnians in Utica and in Bosnia to explain what sparked that war. They described generational memories of violence that had happened long ago—conflict between their forefathers and the forefathers of their neighbors. They talked about why their country was split along religious lines even though people there shared the same ancestry. They remembered the years before the civil war began, when minor slights among people who were once friends were whipped into serious grievances by nationalists on both sides.

Sounds to me like “ethnic tension” is the _right term_ to use and they’re avoiding using it because of political correctness
