I think I lot of people use the term QDM to justify killing as many doe as they want. They never take into consideration what the buck doe ratio is or what the herd size is in relation the caring capacity oft be land they just think QDM means shoot does. When actually you should only shoot them if they need removed from the herd due to the herd being out of size in relation to the caring capacity of the land. Most clubs also will not take the time to record data that would give them accurate fawn recruitment rates which is a major factor in determining harvest rates of does when needed. And they have unrealistic expectations on the size of bucks they will harvest in AL. If you can get all these factors in line yes QDM will work.
There's truth in your post, some do use QDM as an excuse to shoot every doe they can get their crosshairs on. Just like some use "cull buck" to shoot bucks of less quality than is being managed for on a particular property. I know some "QDM hunters" who do both, but I will not hunt with them. A little knowledge can be a bad thing sometimes.
