I agree that everyone sees race, I don't say I don't notice a person's colour. I'm saying it isn't an important aspect of a person that I would look up to, befriend, or make any other judgement upon.
Perhaps you don't fave racism toward black people, and perhaps that's why you are so annoyed by it being treated with such importance. Why can't people stop treating it as some big thing, and just look at each other as people, and reduce the conflict, you might ask.
People tend to project, and to have their own experiences and views color how they see issues. Sometimes that's 'good', sometimes 'bad'. Liars and thieves tend to think everyone lies and no one can be trusted. 'Honest' people tend not to see corrupt politicians for what they are, and to give them much too much credibility for 'good intentions'.
I strongly oppose racism rationally, but I've come to realize that despite this, I have some racism in me - how I 'feel' toward people. It's hard to change how I 'feel'; but then I can choose what I do. If I see a black person and think something negative, I can instead talk to them in a friendly, respectful way; I can fight for good principles, for their rights.
And people need to learn to listen to others a bit, and realize their experience might be different. If a black person seems obsessed about racism, that might be largely because they have a different experience with it. That doesn't mean they're always right about it, that they can't make mistakes, but it doesn't mean their having different views is wrong, either.
I remember a time when a lot of Canadians seemed to care a lot about 'acid rain' coming from the US. A lot of people in the US really did not care. It didn't affect them. Perhaps that's an analogy that might have some resemblance if you're someone who doesn't feel or get subjected to racism, to how you think others treat it too importantly.
I will admit I've had a thought at times 'man, black people seem way too obsessed about racism'. And then comes a bit more learning and thinking and realizing some of what I said above - and a need for me to support justice for them. They way to have them less obsessed by racism isn't for them to shut up, it's for racism to affect them less, which we can help with, a little. Like voting for politicians who will support justice, not pandering to whites.
This is one example of a more general political problem. You can see it pretty universally in cultures. India with history of castes, Japan's racial superiority over other Asians, Russian sense of superiority over some others in the region, pretty much anywhere.
If women weren't half the population, and playing a big role in men's lives, would their equality and right to vote have been finally more respected as they have even now? A basic issue for politics is how to get 'universal principles' respected, so majorities support justice for people even when they're not affected. And the 'annoyed' people who fight against that justice not because they're really against it, but that they aren't affected, are a problem.
