Here's the issue. For the sake of argument, let's just say Barack Obama was correct in what he was saying. Was there any reason to be yelling at the elderly lady questioning you? Sure, maybe it ruffled his feathers. Sure, her tone was a little confrontational. So what? As President, many many people will be doing exactly that. Every time someone questions Obama or gets a little confrontational with him, is he going to lose his composure and yell at them, too?
