Diane Abbott’s twitterstorm-provoking comment was wrong — factually. And that should be all that matters.
The claim that “white people love to play divide and rule” is clearly unlikely to be true since there’s no reason to believe that the content of one’s character is related to the colour of one’s skin.
She ought to have gathered some pretty strong data to the contrary before thinking about making that statement. Since she doesn’t, then the only response is to ignore it or to correct her misconception, and, in either case, swiftly move on.
The problem is not racism, “reverse” or otherwise. It’s the casual making of unevidenced assertions. Diane Abbott is no more guilty of that than most MPs — or most people.
