It's A Grand Old (Put Away Your) Flag

It has been my long held belief that nobody over ten should be allowed to wave a flag in a football ground. Security guards should be detailed to grab the things and snap them in two as the user is clearly not in any mental state to be carrying a metre long pole. 

And so, from the media coverage of the Round 9, 1909 game against Collingwood

Any person waving flags or banners inside the ground or stand enclosures will be expelled 

Who said the world hasn't progressed in the last 100 years? I'd say they knew exactly what they were doing. After the game

The committee were commended for their decision with regard to the waving of flags. It was contended that the flaunting of flags is more likely to lead to a disturbance than anything else connected with football. The supporter who considers it necessary to show his devotion to a club in that way is generally a weak-minded barracker whose support is rather baneful than helpful, or possibly one of a "push" deliberately inviting a disturbance. This year the foolish fad is very noticeable, and leads sometimes to fighting but more frequently to abusive and foul language". 

I invite you to direct 'abusive and foul language' at any grown humans you see waving flags at the ground this year. Whether or not you take this to heart and wade into the cheer squad throwing haymakers is your business, but remember this the next time some 40-year-old tosser almost takes your eye out while swinging one of these things around.
