Out of curiosity, I just typed; 'white kid stabbed by blacks' into Google. Guess what comes up? Pages of reports describing black people being stabbed by whites.
We are witnessing the systematic demonisation of the Caucasian race, and the ongoing marginalisation of straight white men in particular, who are blamed for all the evils of the world and no longer have a voice. Any white man who disagrees with or challenges the opinion of gays or 'people of colour' is immediately shouted down as being racist, homophobic or whatever suits at the time.
