There is absolutely NO reason for butterflies, earthworms and all these other silly things you suggest, to be hunted. Foxes ARE a problem, and need controlling. Hunting butterflies for the sake of it would be unnecesarily cruel.
I am against game shooting as the birds are bread only to be shot, which i think is cruel. I know people who shoot game, and i dont impose my oppinions on them.
However, i think banning pheasant shooting etc, would have a detrimental affect to the countryside, as shooters put a MASSIVE amount of money into farms and estates, and do a lot of good forest work.
In the same way, i think if fishing was banned, the waters would be in a worse state, and there would be hardly any of them. Many lakes etc were made for fishing. Excluding the filthy fishermen that litter the banks, and destroy their own sport, and get a bad press for angling, many fishermen help alot in preserving the waters. Organizations such as the Salmon and Trout Organization, and the ACA (of which Chris Tarrant, is the chairman)

Shooting rats is valid, they are vermin. Many people shoot rats with airguns, and many countryside people keep ferrets or dogs for killing rats in the barns. Rats are filthy, and no one wants them around.
In the same way, they hunt foxes. What are you getting at?

i think most people percieve foxhunters to be upper-class, and resent them for that reason. I can 100% tell you that none of the people i know are "Toffs." Most of them you would NEVER guess hunted. Just ordinary people. Many have got into it from riding horses, and are invited to go on a hunt.

all the best
