I'd go further and say that "whiteness" is just a form of the otherisum. A mechanism for establishing in and out groups to determine the potential for favorable and unfavorable social relationships. Whiteness is generally defined as people that look like, speak like and behave like a greater homogeneous population group. Each homogeneous group sets their own measure (bar) for inclusion. For instance. not all light skinned Europeans meet the standard for inclusion in small American towns. In general, the smaller and more homogeneous the population, the smaller the genetic ingroup.
