I'm with you.
I doubt anyone would have a problem with stomping an aggressive 'Possum. But he killed something "cute", and that's the worst kind of sin with the "animal lovers".
I have popped my share of geese with a .22 or shotgun, but there is something wrong with a guy that stomps baby geese to death because he is scared of them.
"Aggressive 'possum"? In my experience no such creature exists. Opossums are by nature peaceable creatures and are utterly incapable of aggressive action. They also cannot carry rabies. I don't know how you define aggression, but I've yet to see a 'possum do anything except scurry away, go limp, or slobber profusely in response to my presence.
Opossums are beneficial creatures and are harmless to humans, property, and livestock. Please don't stomp them!
Right, because when you get to stomp and kill an ugly animal, you get to triumphantly stand over it's body and proclaim yourself the big, manly beast-slayer, eh?
Can't do that with geese...
