It just seems to me that if HN is going to discuss this, there should be something HN-ish about this and not simply a general, non-specific rehash of a jillion other discussions about the participation or lack of participation by blacks in tech.
"Has YC ever founded a black founder?" seems pretty specific and HN-ish to me.
I'm certainly not going to complain bitterly if the discussion leads to positive change.
Fair enough. What a sad picture in your post.
