As it happens the DM did run the Sep 2011 story about "RBL poppy sellers being banned from city streets because of council red tape".
That is certainly not the same as the RBL avoiding areas to avoid offending "minorities", but it rather looks as if it was this truthful story which was then exploited for purposes of misinformation.
Regardless of Load_Toad's personal opinion of the DM, I didnt interpret his post as actually blaming the DM for this particular outrage bus, but making a general point. Most of us managed to work out what he meant:
Does every act these days have to be a Daily Mail outrage piece and chance for a war?
Back on thread. This was a particularly irresponsible outrage bus which exploits people's commendable wish to observe remembrance and honour the armed forces.
I would like to think that the OP has done us all a favour by exposing this malevolent rumour.
