Correct. The evidence isn't exactly overflowing but what little there is indicates the Clovis migration was not a peaceful one and existing populations either met a violent end or were forced to move to areas where their populations couldn't be sustained and slowly died out.

The parallels to the European genocide of Native Americans has significant consequences to two groups of people. The first is the white supremacists/edgelords who think an invasion from thousands of years ago means the actions of colonial Europeans as well as ongoing social justice issues with native Americans/reservations are somehow justified or deserved. The second is the far larger but far less dangerous group of people who think native Americans are somehow inherently morally superior and/or that European colonialism is responsible for all the world's problems. To them it's an article of faith that aboriginal peoples do not and cannot commit large-scale atrocities.

These two groups can make discussing and teaching American pre-history very difficult.
