Not political at all... I have supported every single NPL club we have faced and, in the last decade alone, I reckon Ive been away to over 20-25 different NPL clubs around Victoria, paid my entry, bought food and drink, engaged with the home fans, had a laugh, cheered on my team and been made to feel welcome and respected... Clubs who are dreaded rivals, with fans who give us a very very hard time and often hostility during the match tend to be the most authentic, respectful people and I will happily spend my dollar at Somers St, BT O'Connor, Paisley park, Frank Holohan, OV, Dandy Thunder, Hume City etc etc etc...
Oakleigh, once upon a time, was a small community club backed by Greeks. No different to others like Port, Box Hill, Malvern City, Northcote, Bentleigh etc etc.. - Shit I even played two season of juniors there in the 90s. You're right in that most of their curent baord and fans where once regulars at Middle PArk or Bob Jane and visitng Oakleigh was a friendly match and atmosphere.... WAS.
Something happened to them about a decade ago. Visiting their ground is NOT enjoyable and if their self awareness is so lacking that they think it is ONLY South Melbourne fans that think this, perhaps your club should ask members of most other clubs around the NPL VIC why they feel the same way towards Oakleigh that we do?
