Y'know, if you'd said right off the bat that only the white nurses were given the manual, I think you'd have fewer people disagreeing with you (eyebrowing over the combative tone, yes, but not disagreeing). However, while that is pretty darn outrageous, the logic of a lot of your comments seems to boil down to, "Individual ____ people have been racist to me/taken advantage of efforts to be culturally sensitive, therefore there's no reason I, as a white American person, should have to make extra efforts to be sensitive to ____ people in general." Which, um, is not logical, sorry, and has next to nothing to do with how you were actually wronged by being given this manual.

Also, in several places you seem to be conflating cultural dominance with numerical dominance. And assuming that every other white person in America has had the same cultural education as you. (No, it's not obvious to many people that 'African-American' is largely not a preferred term.)
