Racism exists in all races, and it's something that goes in both (er, all) ways--it's not as bad as it has been before, but it still exists and it's still a reason for concern. Racism can often lead not only to just harassment, but to physical violence, and murder. Racism isn't purely a problem in the US, nor is it at its worst here--it's easy to forget that genocide is still ongoing in some countries. Racism is, or should be, one of the most concerning types of discrimination.
