I think it is an issue.
An issue thats most politically incorrect but when you start changing yourself to become politically correct you arent refining yourself. you are becoming a politician. A shell.
Dont get me wrong, there is most definately loads of agro people out there who arent aboriginal. Its just the sheer majority of cowardly 10 on 1 style attacks that I have witnessed or heard about involve them.
I have had my own experience and know other good friends, one who has been "glassed" from a broken beer bottle after it was smashed over his head and the other who was repeatedly hit with a cowboy belt with the large metal buckle end.

Back at a tender age of about 13 I was attending a Blue Light Disco. Yeah Yeah give me some shit but everyones been to one

Anyhow as you know these are police sponsored/supervised events where kids are supposed to be allowed to dance and have fun without threat of danger, drugs or alcohol. It was actually held at a Police and Citizens Youth Club so ever staff member was or had a history in the force.
After enjoying myself with a group of friends for most of the night I found myself sitting down on a chair resting and looking out the large glass wall panels inadvertently catching the eye of the "leader" of a group of about 10 aborigines who were just loitering outside. I tried to look away but it was too late and they came up and started hitting the glass windows and yelling at me from outside, they tried to come in but the "police" wouldnt let them.
After the night ended (at about 10pm or something) I was standing with the group of friends chatting and laughing about the night when out of nowhere one of the little "wabbos" (white homie dude who hanged out with them) came up, grabbed me and pushed me down some stairs.
There was literally at least 100 people standing around and no one helped out..this was including police and parents coming to pick up their kids.
when i got up i was treated to 2 punches to the head before i had time to react and I went into flight mode and tried to bolt. As soon as i turned and ran the rest of them jumped me and started punching and kicking the hell out of me. 10 of them all aged around 16-18 beating on me, a 13 year old.
Cutting a long story down it was eventually broken up after about 10minutes and i was told to leave without ever being asked for my story or if i wanted to press charges.
Since then I have found myself predjudice towards both police and aborigines. Its the way I am now.
Before that night I was actually wanting to be a cop when older and at my older school was good friends with an aboringal boy so its a shame that an incident can change me for the worse like that.

As for avoiding trouble? I did carry a knife around for a while after that simply because I was scared but it only took about 6 months to learn that wasnt cool at all and if i ever did use it would get me in more trouble than i needed.
I guess all that you can do is avoid trouble spots, walk main well-lit streets, hit the gym and learn a fighting skill.
Im not tanky by any means but because im so tall (6ft3) and have large shoulders people generally just dont start on me anymore. If you can beef up and make yourself look like more of a challenge it seems to scare them away.
Agro people suck. Id like to stress that I hold nothing against virutally any other person...be them black, white, yellow or a sort of transparent flourescent green colour.
But im not apologising for my loathing of aborigines. Not to anyone.
