Im fairly certain the specific individuals were identified when the term 'nigger' was used.
You ask what the benefits will be. I respond...consider the alternative. The alternative that is everything the nigger infests turns to shit. Every example of a once great non-nigger city, neighborhood, country, or any other instance of previously being non-nigger, that became shit once the nigger infestation began.
For your referencing pleasure:
Haiti. South Africa. Rhodesia. Any formerly non-nigger neighborhood. Any example of section 8 housing. Detroit. Atlanta. The list is only as long as the number of nigger populations.
Anyone that wanted segregation eliminated didn't live in the same areas as the niggers.
