Looks like I fall into the "other" category.
I usually find myself killing a few Does or more each year. Not because I have a deep seated belief in QDM, but because I just enjoy killing and the entire process, gut'n, drag'n, all of it. Killing a bunch of Does has made me a better hunter and filled my freezer with good food.
I also feel it's important to keep herd numbers at a reasonable balance. No sense in there being so many that they're always getting greased on the roads. Lots of people get hurt in the process. I had to care for a person who was killed in a motorcyle vs. deer a couple years back. That'll give ya different outlook on high herd numbers.
As far as bucks, I live in Iowa so the opportunity to come across an older deer is there. I don't really consider myself a hard core trophy guy, but I do try to wait for a good'n as long as I can. Having antlerless tags in my pocket also helps knowing I don't have to kill a buck for just for meat.
In the end I never know what buck I'll take home until I see him though. Usually try to kill nice heavy 2 y/o or something bigger. I've gone some years and not shot a buck either. All I know is I'm have'n fun. Make it what ya want, that's the important part.
People shouldn't get to wrapped up in big deer IMO. A good portion of the time the real difference in killing them is just the area you have available to hunt. Nothing more nothing less.
