From my memory you only saw her legs... with the occasional broom. She spoke like a black person (voice actor was black) and she did maid stuff.
Yup, racist.
EDIT: Did it cross anyones mind, before this thread, that T&J was at all racist?
Well you've not actually taken in what I've said. It's not that she was black, and a maid. Why are you fixating on that? It was the stereotype depicted that is the issue.
I watched Tom and Jerry with my nan growing up and always felt off about the maid.
