There are people that say the best way to get rid of racism is to stop talking about race. I have always wondered what made people think this would stop racism. Can anyone explain the theory behind this approach?
I can't speak for these people per say, but I do understand where they're coming from.
First and foremost, you'll never get rid of racism. As long as there are people who look significantly different from some people while looking significantly more similar to other people, there will be racism or some 'ism akin to it.
I can't abide by the thought that we should "stop talking about it", but I will agree with those people insofar that I believe our cultural lexicon often lends itself to mainstream racism. A lot of it is based purely in ignorance, and not the typical racial ignorance, but ignorance of innocuous things like names. People don't generally know the name of the guy who invented gun powder (myself included), and so they say "The Chinese invented gun powder." People don't know the individuals they saw on camera looting the liquor store in Ferguson, so they say, "the blacks in Ferguson are rioting." Sometimes it's simple practicality. Rather than list each country or, better yet, specific leaders and individuals who committed which specific atrocities, we just say, "the white man did X to the natives".
And sometimes it's just ethnic pride and the individual's need to justify their importance. "Black people invented rock and roll and white people stole it" is a much more common sentiment than is the list of names of the specific black people who pioneered the style (though, in defense of this particular narrative, I hear "Elvis stole it" as often as I hear "white people stole it", which I still consider silly, but at least a step in the right direction in that it assigns blame directly to the individual believed to be responsible, as opposed to everyone who shares his skin color). Ethnic "ownership" of sports is also a big one. Acknowledging that the greatest basketball players tend to be of African descent is a world away from saying, "Basketball is a black sport".
It boils down to shared glory and shared blame. When we substitute the race for the individual in conversation, it implies shared glory or shared blame for the event in question, based upon ethnic lines. It is literally a subconscious encouragement to have an "us and them" attitude toward race and is completely counterproductive to the ideals of multiculturalism. Ignoring race doesn't change anything, and is totally stupid. That said, attributing shared responsibility based on race, whether directly or via unintended implications, is equally stupid, and totally destructive. Somewhere between where we are now and shutting up about it lies the practical level of acknowledgement.
