Inferring properties about a member of a group from averages about the group is a difficult thing to do without falling into The Ecological Fallacy (http://en.wikipedia.org/wiki/Ecological_fallacy).
Privilege-checking is generally done at the individual level, in all my experiences it includes the ecological fallacy. It's almost always done in a hurtful, inappropriate manner, often in public where somebody is being embarrassed in front of their peers. These are all good reasons to react negatively to somebody so innocently pointing out my privilege.
