I don't think chasing a fox with hounds, horses, humans and cars IS an effective way of culling foxes. And those that miss the hunt now have their day out with a drag hunt anyway. I really don't see the issue here.
Even if there is no pleasure derived from a kill, there is a sporting element attached to a hunt (fukc knows how) and enjoyment is derived.
The "issue", for those of us who truly love and respect animals for their own sake, is that the Hunting Act is a piece of bad legislation, brought into being through class politics rather than a true concern for animal welfare (as evidenced by the total disregard for the input of veterinary professionals into the White Paper), which is impossible to police/enforce meaningfully and which has not saved the life of a single fox. All it has meant is more foxes wounded by the gun and dying the resulting unpleasant death or controlled by farmers taking matters into their own hands and employing equally illegal but more stealthy and less humane methods.
