This was a number years go, but here goes.
Back in high school (in Southern Ontario), in a geography class we had to choose a subject for a final project. One of my classmates did animal rights. During the presentation they described how hunters would "shoot animals in all four legs before killing them" and other such junk. During the entire presentation my whole class was dumbly nodding along as if it was obvious that hunters were cruel barbarians. At the end of the presentation I called them out on it in the most polite fashion possible, asking them to verify that information (they'd gotten almost all their 'material' from PETA) and finished by saying that I was a bowhunter and had never even heard of such a thing. I also pointed out that hunters are required by law to recover all useable meat on the animal, and that most of the behaviours ascribed to so-called hunter in the presentation were in fact against the law and those hunters were therefore poachers.
Dead silence after that - I was the only person in my class who hunted , as I grew up in a city. But I think I gave people a new perspective - being polite, respectful and articulate is surprising to people who expect you to be bloodthirsty and stupid. I may have changed a few minds, though I didn't make any friends among the presenters!
As far as recently, I run the archery club here on Manitoulin Island, and try my best to get kids into archery and bowhunting (while still learning, myself).
