Gosh I'm terribly sorry if my answer didn't satisfy you Quinlad but “reverse racialism” was not my phrase. I was simply attempting to explain what I believed was meant by the phrase. And from AOG's comment it appears that I hit the nail on the head.
As for you assertion that, “Everyone has been aware that racism is a two-way street...”...

Clearly, both you and I believe the same thing - racism is racism - the colours of the protagonists are utterly irrelevant. However, as you can see in the above link, not everyone agrees with us. (I realise that Jo Brand is not an expert in this area... but the point is made – not 'everyone' agrees...)
Quote, “... as the balance of power has shifted away from white-to-black oppression to a more level playing field, you're might well find more evidence of racism coming the other way.”
Agreed. And the story that this Question is based upon is a very good example of just that.
