They don't seem like professional, paid agitators to me. Read this story in today's Detroit Free Press about our congressional delegation holding townhalls about President Obama's plans to overhaul our healthcare system.
Despite what advocates say, the protesters are just ordinary Michigan folks who haven't been sold on moving our healthcare system down the road to socialized medicine. They're not sold.
Such enthusiastic protest has been vigorously practiced by Democrats over the past several decades. They have shouted down speakers and disrupted meetings too numerous to count.
It's just democracy at work. Sometimes it's messy and not polite and respectful.
