On Saturday I parked my (almost brand new) car on one of the side streets near Prospect, and when I returned I found a 2m long scratch on the driver's side of it. I am presuming it was done by an angry North supporter, seeing that I have my Glenelg stickers proudly displayed on the back window. (although I guess there is the possibility that is was just some stupid kids who had nothing to do with North)
So it makes me wonder

Was I unlucky and this was a one-off incident, and I shouldn't worry about displaying my footy allegiance on my car?
or

Am I foolish to display stickers on my car, knowing that there are a number of so-called "supporters" (from various teams) who are prone to this sort of despicable behaviour?
It is a pity if people feel that they can't display club stickers on their cars, as these are great free promotional tools for the SANFL - makes people driving around realise "oh, there still are people who really do care about the local league"
I would be interested to hear other people's views on this issue.
