I am vegan and must hope any lessening of suffering happens. I hate hunting, but know that a dairy cow is far more likely to suffer far more than a deer a hunter shot. I’d be willing to negotiate if I knew i could lessen the problem. Case by case, of course. All-or-nothing might make the individual feel holier-than-thou, but the problem is just as bad as before. Idealism is not the same as realism. I’d argue that both can be done - diminish a problem by offering some solutions, but go right back by trying to eliminate that problem.
