When you take over the radio/cable news radio station to make your own program, there is a chance to make such a good show that the security was listening to/watching it instead of doing their job and waiting you at the exit. Doubles as a Awesome Moment.
You can intimidate Conservatives into backing away by yelling your slogan. Which can be anything from "We are the Liberal Angels of Death!" to "...", to "We need a slogan!".
