Man, the internet sucks these days.
I can appreciate the superficial aspect of it - if we're going to overcome racism, we should stop focusing on race. This of course is ignorant to the reality that if we stop talking about race and racism, racism will just go unchecked. Which is of course what (some/many/most?) of those people want.
Unfortunately, I don't think we will overcome racism until everyone wants to overcome racism. More unfortunately, I don't think everyone wants to overcome racism, this seems obvious.
The bigger tragedy is, trying to force-feed "don't be racist" to society just makes some people dig their heels in more, making things worse instead of better. Finally, the biggest tragedy of all is how predictable this outcome is, using force and anger as a tool to change the thoughts and actions of a person/group is generally quite ineffective.
