Like a bunch here, I'm pretty old school because.....well to my grandchildren at least....I'm going that direction very quickly.
As a retired wildlife biologist (11 years ago) I saw the term "harvest" become an alternative way to refer to filling a tag, bag, and yep, killed something. I agree that the term seemed to be born during the period of "Guns of Autumn" and other propaganda efforts by hunter-hater radicals. (BTW, they hate to be referred to as "radicals").
Sometimes I almost use the term harvest, but then stop short because I don't feel like I'm being "honest" enough. However, I can definitely support the use of the term "harvest" when it comes to hunting. As sportsmen and women we (our ancestors actually) demanded the abolishment of marketing shooting (some call it market hunting but I don't). This move didn't happen in time for a few species (bison, eastern elk, passenger pigeon, etc.), but it was soon enough to save(in most places) pronghorn, elk, mules, whitetail, sheep, turkey, and a few others.
Now, thank goodness, we manage the "taking" (another alternate to saying kill) of game species to make sure we don't erode brood stock to the point their populations can't be sustained. To me this is akin to harvest, we harvest a portion of the annual surplus of game animals. So, I don't think the folks who use the term "harvest" to describe the finality of their interaction with one of God's creatures, is a sissy, politically correct, or trying to hide from their act. I could argue they could possibly be deeper thinkers than some others.
I was also a forester. I have definitely killed some trees in my career. Some of those trees were harvested to be used by man. Some others weren't used. They were cut to make room for more preferred species or to release higher quality forest mates from competition.
Bottom line, no more than I will ever criticize a hunter for killing a 50 pound white-tail (if legal), would I think badly of them for their choice of words to describe their action.
Now, if I have a hot button, its the use of
"stick or stuck one" by some who refer to a bowhunters attempt to kill an animal. When I worked in Kansas, a boss, who I liked very much was an avid bird hunter. He knew I was an archery-nut. He made the mistake of asking if I had "stuck one" when asking about my bowhunting success. I asked him if he had perforated or blasted any quail lately. He revered the bobwhite and understood my analogy.
