I completely disagree with David as he says that 'whites have become blacks' which is completely wrong we are all human beings and we all do things that make us look bad at some point, I think it is so wrong to put people into categories based on their skin colour its wrong, the way the world is now its ok to say some words and its not ok to say others, a black man/women can say the 'n' word and nothing be held against him/her but its different if a white man/women says the 'n' word there would be up raw as that would be considered as rasist. There are completely different sets of rules to what some people can say and what others can't.
David is putting them into one category and thinks that it is ok to say that 'whites have become black' when black people aren't a particular type of person or have a specific purpose they are just people like everyone else who have been misunderstood and people are keeping with the same stereotypes from years ago, they think that it can't change but it can, all it needs is one person, no matter what colour their skin is, to change and people will follow, some are just to started to start it off for the future that could be a good one.
He shouldn't have said that if you heard a black man talking on the radio you would think he was white, that is completely wrong they way that people talk comes from where they were brought up such as someone from Australia would/might have a Australian accent, yes certain gangs may speak a certain way but that's because of where they are from or where they live not what they are doing. Race doesn't have a specific voice so he is wrong in what he said and even though he said sorry I don't think that he meant it, he just did it because he was told to.
