In a recent message to all role-players everywhere, Wizards of the Coast has announced that they are taking focused and concerted efforts towards removing the questionable content from their material, including providing some updates to the way the various races and monsters are handled, described, and even created as characters. You can read about this here.
I think this is a very good move.
Starting this week, I will begin (as a part of the 1.4 updates to the material) doing the same in Arcanum. This means not just adjustments to things like the alignments that are assigned to various non-human peoples within the game, but ensuring that the descriptions do not include any reductive racial stereotypes that I may have missed (as a cis, hetero, white, Midwestern, American male). If you see anything at all within the text of the book that is in any way questionable, please bring it to my attention.
