the only slightly racist thing I can think of is the non-Speedy mice, like Slowpoke Rodriguez(?) the one who talked real slow. They were always napping.

I never really found it racist, but I caught part of an episode of Drawn Together and they were part of the kidnapped stereotype cartoons so I guess that's it.

And maybe I'm just being a "priviledged" white guy but I never felt they were racist because when they did get up an do things they absolutely ahnihilated whatever character Speedy was faced with, without getting excited or anything.
