During my 5 years of secondary school, there was a total of 5 black kids throughout my school. Everyone else was white. But no one thought of themselves as white or black, we were all equal, that's not to say we were friends, I went to school with some giant cu*ts. In my tutor group we had a black kid, during an evening he got petrol bombed, it was never once thought that it was because he was black. But, if the media were to pick on a story like that, it would become considered a hate crime, because the media is primarily a business, and hate crimes sell a lot of papers. Much more than random park based petrol bombings in Cornwall.
I think that some crimes are hate crimes, and it's probably more white on black than black on white. White people are generally more pompous and self-loving, I am white btw, so I can admit that.
