I don't see why people will automatically tune Bob off when talking about racism... Well, I GUESS nobody wants to sit through these kinds of lectures... but I think they should anyway. >:|
Really, this just reminds me of all the people who refuse to hear what Bob has to say, just because Bob is the one that said it. That's ignorant, and it ruins an otherwise good point he may have made.
Anyway, I like these introspective looks at words, history, etc., it helps you think outside the box, and you might even learn some new things. I also think it's funny, in a very tragic sort of way, hearing about "the lost city" and it's supposed origins, and the whites throught it was some kind of ancient civilization that went unknown for years to come... without even considering that the humans that already lived there might have built them.
What's even more sad is the idea that anyone on the Internet will deal with this sort of thing in an "intellectually honest" way. Especially the "intellectual" part.
