I have to disagree, but I have several friends that work for places that advocate wilderness like The Wilderness Society that are avid hunters. I will agree the fringe part of some groups are not a friend, but that goes for both the right and left.
Perhaps it is far different in Montana, but I know in my neck of the woods, that the vast majority of Elk killed in the units near me are in wilderness (excluding private ranches). There just is not a lot of action outside of that with the exception of an occasional elk that someone gets lucky with off a 4WD road or the first morning of rifle season. Outside of that if you want real opportunity, better get the backpack together and go in the wilderness or at least to the fringes of wilderness.
