The point is it's all about the right tool for the job.
No one with a brain in their head is going to argue that an air gun's a more effective tool for killing things than a fire-arm. We live in a small country and as has been said, paths, roads, houses, whatever make a differance as to what we can use.
A good air gun, used with respect and consideration can be a very effective tool. Let's not forget that guns are only tools.
It's not just 'each to their own', it's about what is doable and what's not.
Cheers.
