The concern is that the FNs already have established an end game of excluding everyone but themselves from wildlife resources. Now they are simply using anything and everything that they can as a foothold to muscle resident hunters out of the pie. This is what this is about - not actually anything to do with real impacts of fires on wildlife. It's just a convenient opportunity for them to hammer at their agenda again.
No different than the anti-gun crowd using any gun-related tragedy as a springboard to push their already-decided agenda. Long before these tragedies occur, they already have their responses and outrage formulated and they just simply wait for an event that they can use to leverage their position on.
Of course, if this was 100% about the fires and their impact then more residents would probably be okay forgoing a hunting season for the greater good of the wildlife. But that's simply not the reality of the situation. The fires are just being used as a pawn in a much larger picture.
