I don't think what he/she (I'm not sure if you are male or female, and I don't want to assume) is saying is stupid nor racist. White people can care about the "black condition" because you don't know what that white person has experienced. Maybe that white person, has a black sister/brother or wife/husband or uncle/aunt or friend.
For you to believe that some white people can't care what goes on with blacks is idiotic. Some people can see past color and care about what goes on in a community that is not their own.
Now, I believe that some whites are arrogant and ignorant. But, not all...and to lump them together is wrong. All black people aren't alike, so why would you believe that this white male or female can't care about the "black condition"?
