Unless we're talking about a fabrication, a stereotype is just another word for empirical observation.
It will not be true for absolutely all instances (almost nothing is except the laws of physics), but it's just supposed to tell what the most common observed case.
Without stereotypes (a.k.a. generalizations) there's no science and no discussion possible.
You can fault a stereotype for not being representative (if you have different observations or stats or explanation etc.), in which case it's a bad stereotype, but not for being a stereotype.
