I don't think we need to discuss the merits of whaling, since most of us should agree it is wrong.
I don't. Do I think it's wrong to hunt something to the point of extinction? Yes - absolutely. Do I think whaling, and and of itself, is wrong? No - I don't see any difference between that, and hunting any other animal that we use for food, clothing, whatever.
As for the SeaShepheards .... think of them as the marine branch of PETA. Just as out to lunch, just as misguided, just as full of themselves. And the only reason they aren't murders is simply a matter of luck - and it's just a matter of time.
And I'm sure that when it happens, we'll be hearing cries of "Fascism!" without end, regardless of who arrests their sorry arses, or why.
