Drew, I don't think that defending a person "just because they are trying to make a living" is justified. If you had said they were ignorant or that they had a cultural reason(often the same thing) that would be a valid excuse , but justifying immoral behaviour because its yor way of making a living is indefensible. (Just ask the Saudi morality police or a Taliban fighter. Both are simply "trying to make a living".)
Well, Dave, I refuse to call any other culture immoral for living the way they have done for hundreds and perhaps thousands of years. In the same way many of us eat meat like chicken, pork or beef, many other cultures see whales and dolphins that way. There's hardly a case to call immoral if you actually eat meat. Then there are fruitarians who believe plants are sentient, in which case only the fruitarians are 'moral' because they truly don't kill. I don't even know how to comment on your comparison of Taliban religious extremists and making a living except that it makes very little sense.
A fishing village in the Indonesian islands with no electricity and only kerosene lights, trying to make a living catching fish (with non-destructive methods like before the Dutch and Portuguese thought them to use fertilizer and oil for fish bombs, which not many of them do anyhow) and offered pittance (compared to market price) to catch and fin sharks which would be in abundance in the area if it were not for the commercial fishermen who wiped out the area before and the fin traders are merely trying to scrape up what's leftover. These fishing villages have been fishing for hundreds and thousands of years and 80% of them will keep doing that. If that's not traditional, I don't know what is. They do not have the luxury of reeducation for another vocation in Anytown, UK or USA. A little perspective is in order here.
