Okay, so I've only read one page, but I felt the need to add my input; you're completely right in being angered at such individuals. I use the term 'individual' loosely though, because at times it seems like there's a delinquent hivemind thing going on. I mean they're all carbon copies of one another...
I've often heard rather infuriating conversations while travelling on a bus or train. There was once a woman talking to another woman about how her child was being taught Indonesian in his fourth grade class. Now, as far as I know, it's pretty much protocol in Australia for elementary schools to teach the basics of some language or another. Anyway, I'm getting to my point; she was angered by this fact, suggesting she wished her child to learn 'Proper Australian' first.
Yeah... I'm relatively sure we speak English here, lady. Though, she was one of those 'bogans' that overuses Australian slang at every chance she gets.
