Hmmm...
I don't mind the term 'harvest' personally.
In Alaska the deer tags have the words 'harvest ticket' written on them.
While I'm not exactly "PC" myself, I see no problem with the term 'harvest'. In fact, this question has come up before on other websites, and I get the impression some hunters think it's cool to berate the term (harvest) simply to be 'anti-PC'.
I don't think we're fooling anyone by using 'harvest' rather than kill. But I can see negative responses from those folks who are 'straddling the fence' on hunting in general, when we use vulgar, or 'non-respectful' language concering the animals we 'kill.'
After all, we'll never change the minds of the anti-hunting crowd. It's the folks who have yet to form an opinion we need to sway to our side.
I think we do ourselves an injustice by using terms which may convince others that we have little, or no respect, for the animals we kill. These people respect native cultures because those cultures displayed much awe and respect for the game which gave them life. If we disregard that respect, we might push some folks into the PETA camp.
How can that help us?
