Referring to this OP.
This Richard Spencer?
He dresses neatly, eschews violence, and works to sound rational. /.../ In an address at white supremacist Jared Taylor’s 2013 American Renaissance conference, Spencer called for “peaceful ethnic cleansing.” As an example of how this could be accomplished, he cited the 1919 Paris Peace Conference, where new national boundaries were formed at the end of World War I. “Today, in the public imagination, ‘ethnic cleansing’ has been associated with civil war and mass murder (understandably so),” Spencer said. “But this need not be the case. 1919 is a real example of successful ethnic redistribution—done by fiat, we should remember, but done peacefully.”

Seems like he would fail your "simple bright line test"...
The Nazis, notably, also advocated for a "peaceful" ethnic cleansing.
