Sam I have not answered any of your posts, I do read some of them but the answer to this one in my eyes makes you sound like some kind of sadist. You say we are at the top of the chain and more intelligent than the others, true, it is because we are so intelligent and like the thrill of the hunt that there are some species almost extinct, the White Rhino, Tiger just for a couple. Back in the twenties these were being killed for the thrill of the hunt as you say.
As for fish feeling pain, I love any type of fishing, I hope it is not the pain of the hook setting as you say that makes a fish pull harder but the fact that you are trying to pull it the way it does not want to go. If I thought there was that ammount of pain involved in fishing I would have to think about packing the game up.
Surely no-one wants to think any animal is in pain just to get kicks out of their sport.
