What I put up about Celtic fans being awarded by FIFA and being lauded by world renowned players is a matter of fact. The FIFA award was given for their display celebrating the Lisbon Lions.
The Green Brigade don't make up what I would call a sizeable section of the fans. Wiki says they are 500, but I would suggest the actual number as twice that. They are youngsters/students who are labelled a left wing ultras group. However they in no way behave like a typical ultras group if that means looking for confrontation. You just don't see trouble at home games at all. There is no Millwall up here so Scottish football is generally quite peaceful these days
The effigies were cringeworthy indeed, and people remember them as being in extremely bad taste, but on a scale of harm caused at football matches they would be pretty far down the list. The fact that the visiting support that day smashed toilets and sinks at Parkhead (£16k? of damage) is not remembered at all tells it's own story. I think the GB have got the message about the negative image they create and seem to have toned down the banners etc in the last year.
I don't agree with your comments about O'Neil and Lennon, but I'll leave a response for another day. Want to see the next episode of Stranger Things 2.
