Sophist,
I have not read nor had time to go through the information, if it is as swift and humane as you are describing then I will change my view. My issue is simply with the amount of bloodshed. I hunt deer, moose and most other viable game each year, I use the most effective means of killing quickly and humanely. I have never hunted a seal, nor would I, I can only base what I know of hunting the animals I know with what I have seen in media. Therefore I am not as qualified to make a judgement just an opinion, after I read the information you have posted, may I get back with you on the method used?
