Just imagine if we killed cows in a similar manner!
If we drove through fields chasing them, finally firing a harpoon into their sides to explode into their guts and send out barbs to anchor them and we then dragged them around the field on the end of a long line while they screamed and slowly died in agony for hours from their internal injuries.
I think there might be a public outrage.
I think people would demand that the cows were at least killed humanely.
Whales are more intelligent than cows. They have advanced social structures. They have culture. They are gentle creatures. Why would anybody feel it is acceptable to kill them in this brutal savage manner?
