plenty of people enjoy target shooting - which i have done and its requires great skill - Olympic shooters also train with rifles but must train in Europe with pistols because of our stupid laws
I don't think generally people have a problem with target shooting or clay pigeon shooting, shooting animals for sport gets on some people's wicks, but I think what most folks object to is any law like the states which makes it possible for any half wit to go and buy something that will allow you to kill multiple human beings with ease.
In my lifetime I have come across numerous folk, who should not under any circumstances be allowed access to gun.
