I find it amusing when the "more conservative then thou" dears crawl out and bemoan the fact that something is being undone the exact same way it was enacted.
And I find it ROFL funny when people act like trophy animals are not eaten. I would hope your hypothetical friend would laugh in your ignorant face, say he has no respect for the opinion of a fool and walk away.
Then what in the hell did nature do before there were trophy hunters? How in the hell did the herds flourish and survive before trophy hunters? I find the whole thing to be excuses for pretending nature would not in time take care of what “trophy hunting” claims it and it alone can do.
