Obviously, I feel sorry for the victims and it is sad that they died.
However, I'm always very happy whenever Black-on-White crime is shown in the mainstream media. Showing these black criminals and their white victims, forces (white) people to confront the racial reality of crime. As I'm sure everyone on this site knows, if media coverage in North America was truly without bias, blacks would represent the majority of murderers shown, and whites would represent the majority of victims of interracial crime. Simply because, this is the statistical truth.
What might be shocking to some people is that some white liberals will see crimes like this (black killing multiple whites) and try to justify it based on blacks being oppressed, discriminated against, or the history of slavery. It's almost like they feel it's not the black man's fault that he killed several white people. It's actually the white man's fault for oppressing and enslaving the black in the first place.
Unfortunately, A lot of liberal or "mainstream" white people try and ignore, not read, or pretend like they didn't read stories like this, but you just know that its lingering in their thoughts whether they admit it or not. Most of them just brush aside these stories. I actually spoke with a white male at work earlier, and he told me the DC shooting was carried out "without targeting anyone" and "because the perpetrator was crazy". Typical liberal stupidity. I don't even think my coworker who told me this believes in it, probably he just says it because its a convenient "cop-out" for him, rather than admitting the truth which is that this black male was likely targeting white looking people.
Fortunately, though, some whites who are on the fence, will start becoming more and more racially aware.
The best thing that folks like us here at this website can hope for is for more and more people to "see the light", and become racially aware. Personally, one of the reasons I became racially aware as a teenager is because I noticed that crime tended to be perpetrated by Negroes more than other races. I also noticed that the media would often fail to report on black-on-white crimes.
So, stories like this are good for our cause. It violently divides people based on race and that's exactly what we want. As the percentage of blacks increases in places like USA, these types of assaults will be happening more and more. The only positive out of that is that it will likely negate liberal rhetoric and force more realistic perceptions on race and crime, race and intelligence, and race and behaviour.
