I'm not intolerant.

And I am not racist.
Simply, what I am is an individual, one of many, moulded by my experiences and what I see on a day to day basis, thus a product of my environment. An environment that is, beyond a doubt, fixated on racial and cultural divides. Whether it be segregation or discrimination, or political correctness and affirmative action, or just closing your eyes and pretending race doesn't exist.
Which it really does, by the way.
I don't really "get" racism. I mean, I have some prejudices, but that's what life teaches me to survive, and when faced with questionable people and behaviour perpetrated by a very specific group of people, for the most part, I see people, not colours. You show me an indigenous itinerant and I will think the same of him as a caucasian man in the same position. The fact is that I see the former nearly every day means nothing. If any other ethnicity behaved this way I would feel the same way. The fact that I think some groups of people are inclined to behaviour I do not wish to be exposed to, I shouldn't have to surround myself with them.
If 98% of people out of hundreds I'd met from a city, of all colours, walks of life and creeds were all very violent, it's reasonable to expect that the next person I meet from that city will probably also be very violent. The statistic probability of meeting the 2% of amiable, safe people is tiny in the whole scheme of things. That said, it's a survival instinct to take what we can observe, generalise, and take ourselves out of situations that we can predict as likely to end in tears. I'm not saying all racism can be justified by self-preservation, especially not the "pre-emptive strikes" that some people use to validate their cowardly and disgusting actions.
I don't expect every indigenous person to be an icky vagrant or an alcoholic or a troubled student only in the system for the money they get for attending school, or to be a dole bludging, unemployed drain on the public budget, because I have met some exceptional people of Aboriginal descent and many of my family and friends also know people. I'm not suggesting they aren't out there, nor that anyone that does not fit my ideals for social conduct should assimilate, or even that people of other ethnicities are exempt.
Not at all.
Simply, that I am an individual product of my individual environment, and so are all of them, and of us. I just see anti-social behaviour and a constant variable and I know where not to walk at night.
