You do realise you agreed with me. In the world of knowing **** all speak, knowing **** all and not knowing **** all mean the same thing. Strange, but there it is.
I see no problem with criticising supporters opinions. Those who put their opinions across should be ready to have them criticised. A supporter, by definition, is a trifle gobby. Otherwise it would be a less noisy stadium. And as to the so-called bell-ends, if we criticise them to the point where they change their behaviour for the better or leave the world of supporting football, then so much the better.
