@Nullo , you need a history lesson. The NAACP was founded in 1909. During the 20 years preceding its foundation, over 2,000 black people were lynched in the United States. Do you think they should change their name to something white folk would find less offensive, now that we don’t hear about too many lynchings these days?
BTW, there is an organization that might as well call itself the National Association for the Advancement of White People. You can read about them here.
