Yep but the things most humans hunt aren't sapient. They are just animals. They don't have vehicles. They don't have spaceships. They don't have any kind of advanced technology. The Predators are hunting sapient races and that is the point of contention Q is trying to get them to change.
True. But that doesn't change the fact that honorable hunting is about giving the target a chance to escape. Not specifically a
good chance to escape, not a warning ahead of time, nor a fair chance in a fight. Just a chance to flee and live another day.
Even in wartime, which is far more regulated than hunting, there's no obligation to warn any given enemy that they're about to be attacked. You warn the nation, but launching a surprise attack on individual soldiers is total fair.
