Racism affects different races differently. Just because you and your parents choose to not care about race as much as those before you doesn't mean that other races have the same privilege. Those affected most by racism aren't presented with the choice of toning down racism. I'm glad that there are optimistic people like you and your future children, but it seems like (from your post) that you don't get it. That's ok though. The fact of the matter is, racism has been around forever. There are those of us that won't just let it fade away waiting for every White person to take your path.
Racism is a problem for all races. Some races have to live a entire life under the shadow of racism, while others (black, white, other) are privileged enough to only have to live under it in isolated moments.
