I would say do you hear what you are saying? Usually gets your foot in the door. Because it sounds like your saying these people aren't worth helping. . . .

Oh my god, I never knew that their culture was so backwards and ignorant! You know that reminds me of this girl I knew, she got pregnant at 13, had 4 kids by 20, each from different fathers, and abused them all. It really sucked because I felt so bad for her kids, but I didn't know any better at the time, and she was really active in church so I figured they wouldn't let that happen. Anyway, last I heard she had gotten the kids back for the second time after losing control to CPS for using drugs. Oh... wait, im sorry I just remembered she was white. TOTALLY not the same thing right?

"It must have been hard for you to work with people you have sterotyped and have no positive regard or compassion for."

Is that a log in your eye, there?
Perhaps you should do something about that.

So good that white people came here, to bring them alcohol and drunkenness. Imagine them before we came, living like Adam and Eve in the garden.

"as a christian i think you might want to work on your empathy with a people, terribly mistreated in the not too distant past." how does that sound?

"Didn't Jesus hang out with, like, prostitutes and stuff? I thought he made a point of bringing his love and charity to the most downtrodden and sinful, and admonished his followers to do the same?"

[optional addendum]
pause a beat for hanging open of mouth

"Ah, what do I know, anyway--I'm just a dirty, dirty atheist: no wonder I don't put myself above such wretched folk."

Why would you treat a "religious" nasty racist any differently that an ordinary nasty racist ? Cut them off & walk away in disgust...or if you are quick on your feet, quote something from the babble, like "what you do to the least of these, you do to me" & then exit the toxic area.

They were not like that till people like you and me came along love. I can't imagine where they learned it.

I would have to step away. That kind of stuff gets me angry and I don't have a filter.
If I open my mouth at that point, I would have them in tears.

I have a lot of people that I care about that have a different background than I do. My ex-wife is black. My ex girlfriend is Asian.
I've dated all sorts of races. I'm very antiracist and antistereotype

I appologise in advance as I know this isn't an answer to the question you asked. I have had some aboriginal students over the years and some time back ran a cultural interpretation project for Aboriginal Rangers. Generally in Australia we are trying to preserve what remains of aboriginal culture and languages. Aboriginal culture is a mostly nomadic one, following game and the seasons, how can this fit into the industrial culture of Australian society? Last month I was listening to a young aboriginal girl on the radio explaining that to take up a job for wages would be denying and losing a large part of their culture. I agree with her totally. I am a mostly self sufficient ex hippie beach bum, I do not believe full employment should be a goal for society. We need diversity to survive and to make life more pleasant. Why do we homogenise everything, a one size fits all solution looks very boring.

I would have said, :You know, you have no business trying to teach a group of people anything if you do not treat them with full dignity and respect."

To be honest I don't think that is just a Christian thing to say. You may get the same response from many non religious Aussies and Kiwis. I know that sounds terrible and Im humming and harring about actually commenting. There are so many beautiful, amazing, talented and intelligent Aboriginals out there and there are also some not so much.
My friends in Perth and Darwin have many things to say about that. I now sound like a racist asshole which Im not, but alot of that community have various issues I think. I don't mean to sound like a twat. My apologies.

I would say " is that what Christians believe in ? I thought you weren't supposed to judge others?"
Wasn't there a passage about a speck in your eye or something like that ?

The politest that I can get in similar situations is "YOU ARE VERY IGNORANT."

I know how you feel. One of my relatives made the comment "all Abos are lazy", and I had to bite my typing fingers.

On the face of it though, a lot of the points that lady made are factual. I have spoken to several professionals working in remote areas who confirm those points.

The important point is though, that its NOT because they are Aboriginal, its due to the environment they have been confined to. There are any amount of stories of people of ALL ethnicities that revert to this behavior in similar circumstances. Its a "Lord of the Flies" phenomena.

The only solace I have found is that inch by inch, enlightened non-judgemental and educated civilisation is increasing around the world, and eventually we will all be able to participate in quality life.

Apologies. I can't think of a single thing to say to someone like that which could be remotely considered "polite". I am, unfortunately, used to hearing much the same directed at the indigenous people of the US. And black people, and hispanic people, and italians, and anyone else who isn't lily white and waving a goddamn American flag.

"I need to tell you I utterly disagree with you - but cool dog!".

"Ma'me...these people are all your cousins...if you go back in history far enough".

How about, "My dear, your privileged, ignorant, bigotry is showing".
