I think the phrase "defining deviancy downward" more closely captures the concept than "normalization of deviance." The slippery slope of redefining deviance to have lesser thresholds than the prior iteration, and it takes a series of those iterations to truly end up in a situation where the new normal would have been utterly out-of-bounds compared to the original. Normalizing deviance is more akin to deciding that things that were obviously out of the norm are now accepted as a new normal without the gradual degradation, at least in my way of thinking.
