My friends have never had a problem with my lifestyle choices, in fact its a great source of amusement as we rib each other mercilessly about anything, but that's just the Aussie sense of humor. If anyone does get all uppity he's usually labelled a '******'(1) and just ignored untill he 'pulls his head in'(2).
(1)****** = someone behaving like an idiot.
(2)To pull your head in = to stop your idiotic behaviour
[edit] Wow, I didn't realise that word was considered offensive!... what bloody ****** decided it was offensive?
