I find that really disgusting. Even after they are pretty much proven to have been falsely accused and falsely imprisoned you continue to attack them? That's disgusting

It's not necessarily racist, it could have been the same if the five were white -- though I doubt it would have been the same. That's like concluding that someone who is against illegal immigration is racist. It could be that they are racist and for that reason against immigration, but it could also be that they are just against illegal immigration. Sometimes the motivations are clear, sometimes they are not.
