Where I live, people have a similar view about hunting. Senseless slaughter of something you can't eat, and killing does/fawns you need to grow and repopulate the species is frowned upon. Ground squirrels and coyotes are exceptions, because they are both numerous and a threat to livestock. Coyotes are predators, obviously, and ground squirrels dig holes practically designed to break legs. Crippled cattle are a lost cause.
It's interesting to see and hear different perspectives from pro and anti hunting people and also from around the world. I guess we all just do what we do and hopefully some of it is good. I like to think I'm a responsible shooter when it comes to culling or hunting but I'm sure there's people out there who would still feel willing to denigrate me for it.
