vynx, I know what you're saying. I can understand where some people who want to "save the animals" are coming from, but while we shouldn't just go around and randomly attack any non-human creature, it is important to instill a healthy respect in them for us. In this country, only domestic animals have any kind of respect for humans. Attacks on humans by bears, cougars, coyotes etc have all been increasing in the last say 20 years. We're no longer predators.
20 years ago, being assertive would have been enough to scare off many a large predator; as the predator knew that the human is a very serious threat. Now however, all humans normally do is shout and scream, but can't back it up with force.
As I'm fortunate enough to live in a densely populated suburb close to two large cities in the most populated state in the US of A, I don't really have much experience with dangerous animals (though I had a near run-in with a very large mean and scary dog a few weeks ago). I can tell however that even geese and ducks have no fear of humans. When I was a kid I remember 3' tall geese coming far too close for comfort, and now they will literally attack a kid with food.
