Imagine that you get your wish that this whaling should be made illegal. It has been stated that a majority of the islanders oppose any banning of the activity. How could they be stopped? Obviouly under these conditions only by the application of exterior force upon them. Should Denmark ban it and send over police to fine, beat up, and/or imprision anyone who dared challenge the prohibition (for that is how unpopular laws must be enforced)? Or perhaps promote an enbargo on the Feroe Islands, living conditions of its human population be damned?
In other words, how much violence agains humans is acceptable for the sake of avoiding needless suffering by animals? At what point does demanding instruments for the protection of some animals makes one a sociopath in regads to the humans who want to cause the claimed "needless suffering" upon those animals? (needless, one should keep in mind, is a subjective judgement)
