Yes, some Native American tribes treated the settlers badly too. (Even then, there was conflict within tribes regarding how to deal with whites.) But there was an order of magnitude difference in the amount of violence perpetrated and the amount of harm caused.

The "documented atrocities that certain Native American tribes committed" against INVADERS, you mean? Because it was their land, and the word "settlers" is a way to whitewash what people did to them - and are still doing to them today - which is invasion and genocide.
