I disagree strongly that we all have to stick together and that the end of dog hunting will be a foothold to end other hunting. I'd have to say that unethical behavior by a highly visible group of hunters is a far more dangerous thing.
I do agree strongly that we have to police ourselves, and those sub-groups with the highest visibility especially so. Sorry, but I've been in high visibility groups myself on the professional level and that's just how it is. Just digging your heals in and saying we're all in this together won't cut it, but finding ways to police and discipline your own type of hunting will. Until dog hunters figure this out, they are going to be attacked.
