Humans are not in any way homogeneous, though. So, not only are people not necessarily all incapable of accepting criticism, those that are will have different reasons for it.

Though, based on this comment, it seems you’re dealing with people who don’t like it when you don’t universally massage their ego.

In which case, those specific people you’re thinking of have tied their self-worth to their perfection. Tell them they’re not perfect and they get tetchy.
