Ethnic cleansing: "with some researchers including and others excluding coercive assimilation or mass killings as a means of depopulating an area of a particular group"

"Mass killings" is a big detail which is hard to overlook. If we can't agree where ethnic cleansing includes mass killing it's hard too agree if ethnic cleansing is taking place.

Personally, ethnic cleansing to me sounds like Rwanda or Yugoslavia, which is not happening in the US yet.
