Sorry if you misunderstood, I was in no way suggesting you were telling people when and where to discuss racism, but there are people in this thread doing that exactly, though I repeat not you!
I think in response to the bolded bit I think, yes, it is always legitimate to look for potential racism when there is a public furor around a PoC as you said earlier our knowledge of the UK (tabloid/right wing) media means that we should always be on the look out for their direct or indirect racism.
But I don't think anyone has suggested that racism is the explanation for this reaction apart from that one poster in just one post.
And as for the Greenwood thread, firstly these are two very different stories and I wouldn't want to conflate or compare them in anway. But I think it's fine to examine the reactions for potential racism. Doing that in no way condones or belittles the actions of the individual, I think alot of people here can't understand that though Zouma has done something terrible and we can all agree it is horrendous behaviour, the response can still have racist overtones and as such that is worth discussing whether you believe it or not. I would say exactly the same for Greenwood.
