Of course. Generalizations are perfectly fine as long as they are about a politically incorrect group. i.e. all men are rapists, all white people have privilege, etc.
I don't want to be anal, but if you put 'all' before it it ceases to be a generalization, and can be disproved by simply finding a single man who has not committed
**** or a single white person who is not privileged.
Well, except the term 'privileged' used in this context is entirely subjective.
If you upset a blonde she will cry. If you upset a redhead, she will make YOU cry. Are these generalizations? Sure. Not entirely untrue, though...
