If you want, you can always find something racist I think. I watched 'genesis' a few weeks ago, and it occurred to me that everybody seems to be devolving but
Geordi. Perhaps they wanted to convey the message that there was no 'room' for him to devolve into something more primitive ?
(Not being serious, of course, just trying to make the point that one can try to see too much in an episode). I think I agree with SonicRanger, that it is just the result of some ill-considered choices without the intent to be racist.
