Yes, I think I read one of your articles and liked the usage. If I were king, the term would be “White Insouciance,” a nod to King Henri I of Haiti, whose palace was called Sans Souci, because “without worry” really captures what White people have going for them. But neither your choice nor mine is going to supplant “privilege.” That word has a valuable pejorative connotation, and virtually all the rhetoric associated with anti-racism today seeks to expand denotation without losing connotation. (How can there be an inadvertent “aggression,” micro or otherwise? The accurate word is “trauma,” but it just doesn’t have the juice.)
