UNAMERICAN?

I want to make a quick comment about something said.
Nancy Pelosi (Speaker of the House) had these words today...

"These disruptions are occurring because opponents are afraid not just of differing views — but of the facts themselves. Drowning out opposing views is simply un-American. Drowning out the facts is how we failed at this task for decades."

This was just part of the entire editorial in the USA Today here is the link: http://blogs.usatoday.com/oped/2009/08/unamerican-attacks-cant-derail-health-care-debate-.html
How can the Speaker say that American who voice their opinions is unAmerican? The liberals were very vocal in opposition to the Iraq war.
Americans want to be heard and they are not listening. In your normal life if someone is ignoring you and you want to be heard, what do you do? Talk louder right.....
Let me know what you think!!!!
