Absolutely no comparison. Fox hunting is banned. So you think a dog killing a fox(natural instinct) is worse than a Spaniard throwing live animals from high buildings?
There's nothing natural about a group of fat blokes and posh old women on horses training a pack of dogs to hunt down a wild animal for fun. The act of a dog ripping a fox to shreds may be 'natural' but the situation is entirely artificial. It is also far from banned in practice (hello trail hunting) and I know this because I sab hunts.
In my view they are totally comparable.
