That doesn't make sense when I wish to draw attention to a very specific part, the most important part to my point - which is that I think your tone is what is raising heckles, not your opinion. I haven't taken you out of context.
It's your choice how you want to come across on a forum but none of the replies since 9am (UTC) yesterday would have happened if you had just posted 'Australian dollars' and no other words at all, heaven knows the forum has plenty of very terse posters as it is.
There's loads of people that flat-out can't stand each other on these forums but it is ordinarily quite civil. Lots of users get on other user's tits constantly but stuff mostly comes out OK. There's no group mentality on the forum except one of generally just trying to do right by one another, and assuming first that there was a misunderstanding rather than an outright attack on your being, if a post reads sour.
