"you described is very rare (I would think), as in a white person is unlikely to be killed for just being White, as opposed to the cases of non-White people being killed for being non-White."

Well here in the UK it is very rare for anyone to be killed simply because of the colour of the skin. Black people are proportionately much more likely to be killed than other groups but the vast bulk of them (about 88%) are killed by other black people. This is probably not so much a straightforward race issue as a class issue. Most of the murders take place in deprived urban parts of London and Manchester etc where a fair proportion of the population are black. Of the 12% who were killed by non-blacks (which would include whites and asians etc) then only a percentage (perhaps a tiny percentage?)of these would be specifically for racist reasons. My point is that every racist attack should be treated the same. An attack on a white person is just as indefensible as an attack on a black person would be.
