No it doesn't. A law does not become racist when one race disproportionately breaks it, otherwise every law everywhere would be racist.
For instance, ACT police are known for not drug testing for cocaine, whereas meth and speed are. (At traffic stops).
This causes the rich, who can afford to take coke, to continue with their lifestyle, and punishes the poor. Using the justification of moral corruption.
For what it's worth, I am Australian, am ashamed of the countries history of treating the rightful owners of the land, but do agree that the alcohol issue is something that has more nuance than appears to outsiders.
Other things that are supposed to address the same issue, such as demonizing social benefits spending with budget control debit cards are outrageous. They are just weapons of the election cycle, and a way to recover campaign funds at the expense to the countries public.
I think you'll find there are quite a few folks that disagree with you on this point, some feel that laws can be considered racist exclusively because of disproportionate impact on specific communities.
Personally I think it just boils down to how people define the term 'racist'. When I was growing up (many moons ago), the term was used primarily to describe intent, but now it has expanded to include outcomes.
I agree that it's important to examine outcomes. It's actually the fundamental measurement of a decision and if we recast 'intent' as 'desired outcome' then its clear why paying attention to it is important.
My problem is that I was taught that 'racist' describes an ugly mindset that would confer malice. That may be true in some cases where outcomes disproportionately affect certain folks, but it's clearly not always the case and implying otherwise just distracts the conversation.
Again, I'm not familiar enough with the causes or effects of these policies to have a properly informed debate BUT on the surface it looks like these rules have been put in place in partnership with the communities in question, in order to try to help what is evidently a severe problem.
But perhaps the reality is different.
(Edit - perhaps I do have the read on this wrong, and these policies were not put in place with community agreement, in which case they should be changed. In other states such as Queensland the 'dry place' legislation is far more voluntary)
I'm not an expert in this field but it seems to me you are vastly oversimplifying the policy and without context. And using language like 'punitive' seems unfair as I dont see how this is a punishment, even if one were to believe it was misguided or ineffective. And I respect this policy has flaws and questionable value, while at the same time feel its fair to recognise it is being done in co-ordination with the community itself and and with altruistic intent.
What are these other alternatives you mention? Please suggest. I suspect they come with a whole set of other flaws and failures as rarely is a solution to these problems without a flip side.
