I'm left handed. I deal with more discrimination on a daily basis than anyone but perhaps an obese person. I demand this world become left handed accessible!
On a serious note, most people deal with their own personal issues based on their physical appearance or physical limitations. Whether you're obese, black, super short, bald, mentally handicapped or speak with an impediment, you've probably felt the same way Keenan did. It's not so much a racial thing as its our inability as humans to empathize with people that are much different from ourselves.
