Lexi,
We're not talking about particularly complex motivations in the case of "Leb" gangs.
All sub cultures are simply birds of a feather, Rockabillies like dancing, hot rods and rock'n roll, cyclists like cycling, Twitchers like the outdoors and native bird life.
"Lebs" like intimidating and hurting people, it's why they get dressed up and go out of a Saturday night, they don't have to do it, they choose to.
Now what we're saying is that there are simply no analogous sub cultures in other ethnic groups which are so uniform or so violently idiosyncratic that they have a profoundly negative effect on other outside the group.
Asians are pretty violent toward one another, so are Aboriginals, Africans and, as you've pointed out so are White Australians but serious predation of other groups is actually rare, except in the case of "Lebs".
You will see Gangs containing White kids getting about but in almost every example they contain a mix of other ethnicities as well, this is why "Hate Crime" laws are so litlle used, it's pretty hard to paint a White thug as "Racist" if he's got a Tongan best mate and a Vietnamese girlfriend.

Dear Jay,

In our country today, there is a widespread, malignant
thought form that "other people are the problem."
Without personal commitment to the attributes of fair play
and integrity, our country is in grave danger. Malice
and intolerance stalk our society, staking claims to our
minds, and not one corner of our social order is
unaffected. What I would like to see happen is that we
remove from our minds the tendency to judge, the tendency
to hate, the tendency to blame. If we could only remember
that we all are human beings - and that we all share this
lovely planet. Wouldn't it be lovely if we could start
the New Year of 2012 with the following New Year's
Resolution:

Don't look to others to change.
Change yourself. Change your mind from an
accusatory one - to a tolerant one.

That would be a good begining to a New Year!

Lexi I'm not close enough to be certain but am close enough to think that the claims about muslim lebanese youth in some area's are not the result of dislike of "the other" by intolerant people not part of that grouping, rather based on a lot of experience.

Too many people from around that area with first hand accounts of the problem, too much well publicised defence of horrid attitudes by muslim leaders for me to dismiss it all as hate speech.

Sometimes it's not ourselves that mostly needs the change. In this case there do seem to be some real problems that are not helped by denial of their existence.

Jay Of Melbourne, the act of tarring everyone in one ethnic group with the same feathers is an act of racism as far as I am concerned.

You are a prime example of an Australian racist, sir.

Dear RObert,

I'm searching for ways to help relieve the
situation. And of course I don't have all the
answers. I'm not denying that problems don't
exist. However, I'm looking for constructive
ways to help.

Lexi,
I wish I had blinkers, wouldn't have to look at so much academic crap then.
