The problem with being disruptive and rude is that it is generally unpopular in America. So in the battle for "hearts and minds" (i.e. for positive press coverage), the intended message can become tainted by the delivery.

Here's one alternative idea: If you can organize enough people for it to look good on camera, a coordinated walk-out could be effective. Tip off a few key press folks in advance, so they know to shoot B roll of people walking out. Then you hold a short press avail in the hall outside the ballroom, delivering a statement with all the people who walked out massed behind you.

It's still confrontational, which the press likes, but it appears more civil and organized.
