That aside - I believe the premise of Hank's post is that it's not a meritocracy in Silicon Valley. It's hard to know for sure whether this is true because there's no way to test this hypothesis. But I think it's safe to assume that VC's are still human, and like every other human, they all have biases, including racial biases. There's nothing wrong with that, in my opinion. However, if they're not aware of that bias - perhaps, mentally, they reject that they have any racial bias because they think that will make them a bad person - then they won't take any conscious steps to correct it. The result would be that fewer black entrepreneurs get funded.
You should realize that being black in America is not like being fat. For most of our country's history, black people have been treated as less than human. It wasn't even until fairly recently in our country's history that blacks gained the legal right, throughout the country, to use the same restrooms and water fountains. Can you imagine that? If you think that that kind of institutionalized racism has completely evaporated, you are wrong.
I think it would benefit you to read the book "Black Like Me" by John Howard Griffin. It will probably change your apparent opinion that black people are a bunch of whiners demanding charity.
