i'm white and i don't find it personally offensive. there is a certain set of risk-averse behaviors that seem ubiquitous among the white (upper) middle class. and maybe this is uncharitable of me, but i do actually think these people feel more virtuous because they do these things, or at least do them to signal virtue. when someone uses a phrase like "enlightened whiteness" or "SWPL", it seems there's a high chance that we both instantly picture the same loosely related set of things that would be hard to describe otherwise.
