To elaborate on this, fanaticism often looks like a great idea to those allied with the fanatics, even if they disagree with their behavior. But people should not feel entitled to fanaticism because they think they are right, because that's how you get people like Santorum. Everyone thinks they are right, after all. It's hypocritical to say fanaticism is a luxury permissible to the "good guys" and not to the "bad guys".
