What Americans ( US citizens ) mostly don't understand is that if they have problem with certain words, because they had Africans as slaves and later as opressed minority, other countries ( mostly ) do not have that same problem- because they had no African slaves/opressed minority, so they are not so sensitive about such terms like Americans are.
Other countries have other words about wich are they sensitive.
On the other hand, I'm sure any politician who would call Obama a "nigger" or something to that effect does know that the word is supposed to cause great offense and probably doesn't mind that. The implications of that particular word are very widely known.
