I wish we could hold people accountable for their actions, but under free speech, you can’t.
Actually, we definitely hold people accountable for the things they say and their actions. For instance, there are likely many people who will not consider joining Terry Jones' Dove World Outreach Center because of his speeches. Lots of people probably avoid him in public. He has certainly been excoriated in the media and in public discourse for his actions. The problem is that he doesn't care. What the senator is really lamenting is that some people don't care what others think of them. That might be lamentable but I don't know what the cure for it could possibly be.
