Wow! I really don't even know how to start on this one. I'm reminded of the remarks made to the Wisconsin State Assembly by the late, great, Rev. Reggie White:
"White people are skilled at organizing things, and business. They know how to get the money.
Black people are joyous and celebrate and are good at having a good time.
Asians are good at math and science. They can take a tv and turn it into a watch.
Hispanics are good at family togetherness. You can look at a hispanic man and he's probably got 20 or 30 people living in his house.
Native Americans were never enslaved because they are good at sneaking up on people."
Unfortunately, White was vilified in the mainstream media for his statements. Let's suppose that, instead of the above, Reggie had said:
"White people are better at guitar and keyboards.
Black people are better at bass and drums."
I'm sure the outcry would have been no less than it was. Those that knew the Reggie White know that he was not a racist, yet he was made out by the media as one due to some observations that he made which happened to tread into the area of stereotypes. White was attempting to acknowledge the strengths of various cultures rather than demeaning any of them. He simply chose an ineffective method of making his point.
Racism in practice wants to believe that human characteristics, tendencies, talents and abilities are determined primarily by race and that racial differences are responsible for the inherent superiority of one group versus another. This is a notion that I fully reject and suspect that an overwhelming number of participants on the forum reject as well. I think it important that a rejection of that set of notions does not cause us to reject the ability to identify positive cultural aspects of particular civilizations and races. I think that Reggie White was trying to make that point. Each culture, if examined, has some positive aspects that it can contribute toward the greater whole of mankind. We would be foolish not to examine these aspects so that we all can benefit from them.
In doing so, we must seek to uplift, rather than demean each other. The OP stated that he did not want to promote racist notions with his question and we should take him at his word. While he correctly noted the potential of this topic to be drawn into a larger discussion of cultural bias, the post represents exactly the kind of question that we should be able to examine without resorting to our worst instincts.
Cultural examination without prejudice, hate and fear can only be healthy. It is when we allow it to be driven by the desire for a negative effect or outcome that we tread into dangerous territory.
In my experiences as a church musician, I(a Caucasian) have been fortunate to have played in numerous churches that were either predominately or exclusively African-American. I can say that I have never felt more accepted or more embraced than at those churches. Often I would leave thinking that I would love it if the church I attended regularly(predominately Caucasian) was able to have that degree of warmth and emotion. In this case, it's a situation in which my observation suggests to me that one culture has much to learn from another in one particular area. Does this make me racist? I think not.
As an example that goes the other way, I was in one church(exclusively Caucasian) which was visited by an African-American family on a Sunday morning. While a number of us in the congregation were warm toward the family, many were not. At the church's business meeting the following Wednesday night, several of us confronted the issue. One man said "I don't know why you're all so upset...there's no sign on the door that tells them they can't come here...". My reply to that man was "There doesn't need to be...the sign is written on your face". My point is that one culture can certainly offer positive elements to another. We should all be able to recognize positivity when we see it and embrace it accordingly while giving proper recognition to the source.
The contribution of the African-American and the African communities to American popular music is immeasurable. It is safe to say that what we play and hear today would be markedly different without that contribution. That, in my mind, is not racism, just fact...and one that all races should celebrate. Are there great bassists from several races? You bet! But, the overall approach to the instrument would have evolved along much different lines without the African influence, and, had that happened, I'm sure that we would all have been much poorer for it.
