would you say that sartres more inflammatory and eurocentric approach is a valuable addition to the book?

Hm, I don't know. I figure that a large amount of the people reading it are Euro-minded, so having something to activate them at the beginning might not be a bad idea. I think it does a good job of targeting western insecurity.

From a purely sensationalist view, I guess it accomplishes something, but from a real substantive view? No, I don't think it really adds something to what Fanon is writing. If I were being uncharitable, I might even say it misrepresents Fanon's argument.
