Benedict XVI is not in the habit of making dumbass comments about Protestants in the first place.
Additionally, Dr. Mohler would probably be the first person to say that comparing him to the Pope is a poor analogy.
Take care that you aren't the first to take offense when someone on FR targets the RC church, particularly if you're going to disparage their church in such a way. IOW, don't complain about anti-Catholic sentiments if you're going to insist on anti-Protestant commentary. It really does go both ways.
