white guilt
a belief, often subconscious, among white liberals that being white is, in and of itself, a great transgression against the rest of the world for which one must spend their life making atonement. It is often exemplified by embracing the cultures and philosophies of various other ethnic groups while neglecting one's own roots.
and
The result of a wide spread racist propaganda campaign launched against European-Americans by various racist groups, individuals, Government public schools and was encouraged by many media outlets in the late 1990s.
The propaganda campaign goals were to diminish any sense of a European-American’s pride in oneself and their community. To encourage European-Americans to feel that the only way for them to feel is self-sacrificing for non-whites and to ignore their own interests. And to tarnish history with over exaggerations, wild claims all while pressuring publishers of books to underplay great accomplishments of history.
Most European-Americans see the propaganda for what it is, however to this day many still hold onto white guilt because it was the way they were taught in school as children and don't realize it is the result of a propaganda campaign.
At the height of the propaganda campaign was the Wichita Massacre, where several black men brutally beaten and murdered many whites in the ice cold feilds of Wichita, the media grossly hid the story from public view despite organizations such as the European-American Issues Forum bringing the case to their attention. Also came in to play was the notion to give greater punishment to whites who commit racial based crimes and ignore racial based crimes against whites.
