I'm with Bill Mahr on this one:
"from Latin... audient-, present participle of audre, to hear."
I don't know if it's the impact of twitter, or what, but I disagree with the concept that it's OK to shout at a speaker during a formal talk. A speech is not a debate.
It's one thing if it's a stand-up comic, or a street performer. It's another thing for a congressman at the State of the Union address, or the keynote speaker at a fund-raiser.
"In an interview later with The Huffington Post, Sturtz, a divorced lesbian, said she didn't go to the event intending to interrupt Obama."
Bullshit. Not a creditable claim.
""Basically, I was asked by the first lady to be quiet, and I can't be quiet any longer"
Then don't attend a speech. Go home and write. Or better yet, invite people to a debate.
