I think that people's political views say a lot more than stuff they own. I consider anyone who is extremely left wing to be NON-bogan, and conversely anyone who holds really right winged views to be more on the bogan side of the fence. There is of course everyone in between and a lot of us are a bit of a mix in some ways.
I come from a blend of both sides in my family. Dad and his family are all lefties, whereas my mum's side are more right wing. DP is VERY right wing. He's a tradie and does a lot of things I consider quite bogan, especially the way he occasionally goes out in public with bare feet, even to the shops which I find horrifying....each to their own :/
DP's bogan-ness is rubbing off on me, can't deny that, but I don't see myself as a true bogan (DP says I speak too nicely to be a bogan, lol). I'm kind of a middle class leftie who, by association, has turned slightly bogan in some ways. The main difference with me and DP is that I can go to a fairly posh event and quite comfortably blend in with the crowd, whereas DP sticks out like a sore thumb, even down to his broad Aussie accent. He's worn a suit once since I met him, and he took it off the second he could back in our motel room.
Anyway so there's my take on bogans.
