Sure, but I think adopting the term non-White into one's everyday lexicon is better for casually planting a seed of doubt in the nearby normie. Similar to how we've abandoned the term "reverse racism" in favor of "racism", because it helps the normie to see that no, race based animosity is not unidirectional. I've had luck with this one first-hand in altering the perspective of a normie.

Choice of words influences thoughts both of oneself and those around you so it behooves us to be prudent with our vocabulary when it's such a small effort for such large potential payoff.
