Beyond a white privilege model
Speaking about race and racism generically hasn't done anyone any good. Though white men dominate and control an unjustly disproportionate part of the church's leadership, face, and voice, many white men in the church and broader society also are the quickest to cry “reverse-racism” and at the slightest mention of racial inequities, many have dismissed concerns as merely “playing the race card”. I would be rich if I got a dollar for every time I had a white man quote Dr. King's statement about the content of one's character not the color of one's skin as the basis for judgment, out of context to me in a way that went against the very logic of the “I Have A Dream” speech, which focused on righting the racial and economic injustices and disparities in America. It seems that the more one is squarely situated in the center of dominant culture, having gained advantage from it, the more likely one is to live in a state of denial in regards to the actual past 400 years, and the continuing white hegemony and racial oppression that pervades our society.
However, people's beliefs and actions are not determined by race and gender in some fatalistic manner. I've known hundreds of white women and men that have opted out of aligning themselves with white dominance, and instead affirm the humanity of all people and have chosen to live lives that resist white hegemony while coming to struggle alongside those that have been most directly impacted by the ungodly racial systems, practices, and beliefs that have morphed and flourished in new and often mischievously subtle ways (though sometimes they have not been so subtle). Regardless, there is a tradition that goes back to slavery up to the present day, of white people challenging racism and oppression, and to not acknowledge those rich and beautiful stories as a parallel narrative to the black determination and struggle for justice and liberation would be a dishonest account of America's troubled history.
One of the inherited terms that arose along the way that has gotten a lot of mileage in aiding white people to become aware of their own complicity and accommodation to racism is the language of “white privilege”. Basically, through various means of sharing, talking about invisible knapsacks, and confession times, white folks have wrestled with the various ways that the current racial order offers white people in general, and them in particular, certain advantages and privileges as a white person. For some people, this has created a moment of awakening for them. They suddenly looked at their life, built on generations of white advantage. They considered G.I. Bills and Homestead Acts by their ancestors, loans received, opportunities to live where they wanted to, access to social networks that included people of means, and on, and on, it went. White privilege has been the banner and primary rhetoric for engaging white people about racism in America.
