Australia has a history just as shameful as any other conquering nation when it comes to human rights and indigenous populations. Things I've learned over the years that more than likely my ancestors participated in or at least gave tacit agreement to are the reason I believe so strongly in equality and understanding of different cultures, particularly indigenous ones.
We still have massive social issues surrounding our indigenous population and no one seems to have the right answer, but at least people are starting to listen, and more are starting to care. We have a long way to go, and if not for people like Peter Norman, we'd have a lot further still to go.
We salute YOU Peter Norman!
eta: I saw this post yesterday, but I've been thinking about what I wanted to say. It's nice that I've learned not to just blurt out what first comes into my mind sometimes these days isn't it?
