You're constructing a strawman. Nobody has said they don't care about black people. The absence of protest attendance or action does not mean people don't care – it may mean they've judged that their talents are best suited to another cause, or that their potential to do good in a different arena is greater. It is a sad cynical state of affairs when people attempting to do good for one cause are berated for not participating in every other cause under the sun. People have finite resources and differing abilities. What have you done to combat heroin addiction? What have you done to reduce environmental destruction? What have you done for Jewish causes? What have you done to improve oversight at the FDA? One could play this game forever.
