First off I believe that Racism, in any form is a learned behavior. We are all Human, For Anyone that subscribes to Judaism, Christianity, or Islam, We are all descendant's of Adam and Noah, we are all related..
Personally I find that direct contact especially one on one, build's bridges, when the Golden Rule is applied. When it is ignored, it can be hurtful and bitter. What does it matter what the color of one's skin is, in relation to negative behavior? We all have different forms of power at different times in various degrees and circumstances. To think otherwise is naive. To think one is not incapable of injustice because of the color of their skin is unrealistic to be polite. If one is not part of the solution, one is living in denial. To make a difference every day in the life of those around you, is what you make it, for better or worse.
You are almost perfectly supporting the definition of racism that i asserted. That promoting division is racism while promoting assimilation is the opposite of racism.
The only way in which we part views is that i believe racism or 'isms" to be 100% instinctive, and that they must be unlearned or intentionally discarded. Or not.
I understand your point with a twist. There is an instinct in most of us that resist's change, anyone or anything that is different, new idea's, competition, overcrowding, not enough to go around, so for various reason's we tend to get territorial and draw lines in the sand or walk around with chip's on our shoulders. Children can pick up on the fear's, insecurities, and discomfort's of elders. that is learned behavior. Faith, purpose, curiosity, reason, overcome the differences in all of us. The Golden Rule almost alway's works when applied. The problem is we don't alway's apply it. When has being polite not a reward in itself??? I'm lucky in the sense that I did have a rough coming of age, and experienced allot of extremes and diversity. I currently live in a community that represents more countries than the UN. White is a minority in my area. Over the year's, building relationships with people, business, work, community, family, friend's, one learn's for the most part to treat other's how they deserve to be treated. Every one except Red Sox Fan's.
