Yes, unfortunately the are seal hunt protest songs. This one is full of ignorance and speculation but his audience is so gullible and stupid that he even admits that in the song and gets away with it.
"At least I imagine... I've never really watched."
That's Rolfie's problem. He's never really watched, he's never really watched the slaughter in his own country as well. Did you notice the white coat in the video? Don't let the truth get in the way of a maudlin line in polemic song or a tear jerking picture in a video.
Perhaps a post card of poor little rolfie warped in the intestines of pretty little calf slaughtered out in Devon so that he could have his steak and kidney pie is what is really required.
