Yes, religion.
Even here, on A2K, there's a marked difference in our attitudes to religion. Most Australians are much quieter about their religious faith, if they possess it at all. I was quite taken aback, at first, when US A2Kers talked of praying for someone who might be facing difficulty in their life. That is something quite foreign to many of us here. Note: I'm not being critical, just a little in awe of cultural differences.
Watching the Schiavo issue unfold & seeing the impact of religious influence in the US has been something of a mind-boggler, too. Sure, I know about fundamentalism, but hey, this situation was truly incomprehensible to me & most other people I know. How could these people & the forces behind them have so much influence?
Sometimes (often) I stay out of debating issues that I'm very interested in & just observe. You see, it's often a debate involving mainly folk from the US. And I've come to the conclusion I don't understand the rules, for reasons I hope I've made clear. However, I'm a respectful person & understand about cultural differences. I learn. But often I don't agree at all as I watch! :wink:
I guess the reason Bruce Petty, say, is far less offensive to many Australians than you, panz, is that we are a far more secular society, overall. We're probably more cynical (overall) too, as a result. What you might see as crassness we might see as directly addressing the issue - with humour & sometimes ridicule even. It's a fact of life here - we're cynical about politics & politicians. And we're often not too respectful in how we express it.
