I was mainly talking about outsiders who Facebook presumably tries to please, like commenters in this thread. It could be that any number of Facebook employees personally wanted to get rid of racist content, but Facebook thought that would be an extremely unpopular decision. Assuming the sentiment across this entire HN thread isn't unique to HN, I can see why they might have thought this would be an unpopular decision and maybe a bit of why they took so long to make it. I'm very glad they decided to do it.
