The suffering of any animal is utterly insignificant compared to the suffering of humans. The Sea Shepard society, groups like it, and their supporters are completely misguided in their efforts as there are humans who could use their good will much more than a whale.
It's genuinely irritating when folks take the stance that their view/special interest makes them a person of stronger moral character. Just because you care about something that isn't important does not a Mother Teresa amoungst savages make. That applies to the uppity vegans/vegetarians, animal rights activists, etc.
I admit that most of these type of people aren't 'in-your-face' with their beliefs, and I'm cool with that. I'm cool with anyone as long as their willing to leave other people alone.
I just shake my head when these 'pirates' drone on about the preservation of life, yet put human life at risk with their antics. I would personally kill a thousand whales if it would save one human life.
Also, as a person who has studied international maritime law, they offend me with their complete disregard for the international collision regulations. If they keep this up, and get a human killed, it will justify the complete eradication of their organization.
