Okay I see the issue this way.
Racism is a disease and the people who hold it are critically ill. I see it as we have three choices,
one: ignore it, let it continue as it is
(doesn't work)
two: hunt them down and treat them to ridicule and punishment
(this only lowers you to their level and encourages them to group together)
three: try to help them change and see on a better spectrum. As they are sick and we should treat them.
(while it may not be easy, or work well at all, maybe we can fix a few. Maybe not many, maybe not entirely, but even if we fix just one we will have done right)
