When a murderer, or what have you, commits a hate crime,
the murderer is trying to socially engineer the community--one in which the hated demographic submits to oppression and terror. When a crime is not a hate crime, the community does not have to fear in the same way. People in a bad neighborhood might not often walk alone at night for fear of being accosted, but that is no way on the same level as fearing being yourself--as in to hide or shield an integral part of who you are (an independant black man, a gay man, or what have you) for fear of physical violence is far worse.
