I haven't had time yet to read all of this thread but I'm commenting nevertheless.
Baggs It seems you are saying you have never seen any news items of, for instance, black football players having bananas thrown at them and monkey noises directed at them from people in the crowd? If so, in the face of such lack of awareness, I wonder how valuable any of your comments are.
I assume Minibags is not black or mixed race. If she were, it is unlikely you would have found DB's actions to be so harmless or characterised people's reactions as being over the top and hysterical.
Perhaps you just enjoy being a contrarian but there are certainly some posts on here - and on the other thread about the new baby - that I would describe as racist. I include in that white people who try to present themselves as "victims" of the "political correctness gone mad brigade" because they see this person's action as acceptable and excusable.
lemongrove I think you will find that there are many posters on here of differing political leanings who have objected very strongly to DB's behaviour. To say that "left wing people" don't care if the royals or wealthy people are victimised is untrue and insulting. I am left wing and a Republican, as are several people on this thread who have expressed disgust at DB's actions. You say you are a Republican too so I wonder how you enjoy being characterised as someone who thinks racism is justifiable if it is directed at the royal family and wealthy people (as EllanVennin described Republicans)?
DB is apparently a left wing Labour activist - that doesn't mean all Labour activists are racists - just that this one is, in the same way that some right wing Conservative activists are racist.
