How is that legal?
Those considerations are always a trade-off. How much government should interfere with an industry, especially one that's been around since we monkeys climbed down from the trees? There isn't just the plight of alcoholics to consider. An advertisement ban would affect business and jobs. It would take a considerable chunk out of the advertising market that when gone world affect media, an already struggling industry. And AA doesn't quite have the deep pockets for lobbying. It's legal because it's complicated, not because it's just.
I happen to agree with you here; ads for alcohol should be banned along with those for any sort of gambling and prescription medication while I'm at it. This "drink responsibly" campaign is an effort to make it harder for lawmakers to decide. I'm reminded of that Soviet Union quote and i'm paraphrasing: we know that they know that we know that they know they're lying yet the lying continues.
One day at a time.
I get it, you're okay with it. And I would allow then to continue funding it if their environmental conscience demanded it. And if they sailed there or even flew economy I'd still allow them to pull a trigger themselves. But I think overall this idea that rich and most likely Caucasian asshole money is required to keep conservation projects in Africa going smacks of a school of post colonial thinking that I don't subscribe to. Africans are not solely motivated by asshole money to preserve their ecosystems.
