It's not propaganda when it's true and for me and is what I employ when I'm hunting. If I believed success was measured in antler inches I wouldn't have passed up a 15 yard quartering away shot at a 2.5yr old buck that would have been my BIGGEST buck ever. I felt successful when I let that buck walk, and I can't wait to get a picture of him next year.
I also felt successful when I shot a 4yr old doe out of that same tree (the second doe I shot that day from that tree). What's more, by shooting that doe not only did I contribute to my goal of reducing the herd, but her 1.5yr old son and her BB son have stayed put. Every other yearling buck I had on film at this location has dispersed. So by shooting that mature doe I helped bring down the deer density, improved the sex ratio prior to the rut, increased nutrition available for other deer by shooting her in September instead of December, and prevented the dispersal of two bucks that I will now get to watch grow up using my cameras.
So you can say I'm throwing around QDM propaganda, you can say whatever you want. But one thing you can't tell me how I measure success. I measure my own success based on the age of the deer, not the antler size. And I know a lot of people involved with the QDMA that share that with me.
