There honestly is not much we can do to completely put an end to this. All humans, although built the same, act and react in different ways. It depends on everyone individually to stop being racist, but there is no 1 solution to this worldwide problem unfortunately. Everyone is going to continue to do them, and there isn't necessarily a way to change that. Sad to say, but this world will continue to be messed up and harsh, no matter what we do to try and help. There will always be problems.
