I didn't disagree with anything you said.
I disagree with the simple-minded nature of the discussion, which anyone with an iota of perception would have picked up on.
I like disagreeing and discussing with people, obviously, or I wouldn't be here. If I want to discuss the same thing 10,000 times over, there's another forum where I can go.
So you don't want to talk about aborigines so you started a topic to talk about aborigines...
Were aborigines discussed 10,000 times over in another forum?
If you start a topic on making an aboriginal day a national holiday you should be prepared for the idea that not everyone thinks that's a good idea, and for them to express their opinion as to why. This is the nature of discussion. You seem to prefer an echo chamber where everyone agrees with everyone. Is your real name Donald, per chance?
