Not all Americans have a last name that would fit into your narrow definition of Alaskan, Black or White. Some Americans are descendants of Pacific Islanders, Mexicans, Russians and sooooo many others.

When you elect to judge one person by the actions of another based solely on their, what? Last name? You diminish your self. You lose credibility in your opinion, you lose respect for your ability to think, you lose the ability to converse with intelligent people, because you show yourself to be lazy and incapable of separating what is, from what you want it to be. Evil does not originate at a person's skin color, it starts in a person's mind.
