So these were a bunch of rude old women. Why is it necessary to point out that they were American? Why was their nationality relevant?
Was one of them wearing a dress? Then why not say rude women wearing dresses. Or rude women wearing eye glasses?
I think there may be some prejudged assumptions made here. The same comments can me made about people being old and rude. If they are rude, then they are rude. Why is their age relevant?
I hate generalizations made about Canadians.
