Generalities aside, I do not deny the accuracy of what you say. There is absolutely no doubt that being born "white" in America, particularly a male, has allowed me more freedom and opportunity than anyone who is not white and male. That's a fact. Regardless of what I thought about the injustice of it to others, I realized that beginning in my teens. It became all the more apparent as I got older. Acknowledging that, and the actual history of this country, now what do I do??  I ask that question, not expecting you to give me some kind of directive (though you're certainly worth listening and talking to) but I ask it of myself, for that is where the responsibility lies.  And as G.C. has said in more collective terms, "how do we get from here to there?"
