Perusing the Crazy Horse Memorial Wikipedia page (just curious to see if it’s finished yet – a big, fat “nope” on that one), and in the “Controversies” section was this:
Having the finished sculpture depict Crazy Horse pointing with his index finger has also been criticized. Native American cultures prohibit using the index finger to point at people or objects, as the people find it rude and taboo. Some spokesmen compare the effect to a sculpture of George Washington with an upraised middle finger.
First, that would be the awesomest sculpture EVER!
Second, one could plausibly argue that the Washington Monument does just exactly that. 555 feet of “up yours, Britain!”
