If it's ok to shoot for the table, what's wrong with actually enjoying it? If you can have fun and eat too, why is that so terrible?
I don't live in the UK, I'm in Africa. Here, it's the difference between hunting lion, say, (very bad), and shooting kudu on a game farms. I think kudu is delicious, and someone had to kill it for me to eat it. But that's what it was bred for.
If nobody ate meat, there would be a lot fewer animals. No farm animals, no game farms etc.
Personally, I'm a city girl and I would never shoot or fish. But if people eat what is shot or caught, and the numbers are managed sustainably, then I see no harm.
It's like the fuss people make about predators. They get upset when the fox, badger or owl kills. How about watching a lion bring down a kudu, or the cheetah take an impala.
And the same person probably doesn't care if their pet cat catches garden birds.
Humans are predators, same as animals. As long as we eat what we kill, we're no worse than they are.
