A good deal of the "enlightenment" quotes are hilarious, but "-Hostage- demands that -Interrogator- stop looking like Hitler." (gotten by giving the target hallucinogens and wearing an imposing outfit while they're still afraid of you) takes the cake.
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!".
Alex shouts the Liberal battlecry! Alex:We need a slogan! Police Officer gets out of there! Security Guard has a family!
If you have enough charisma, you can talk your way out of any encounter. Including the ones with guard dogs.
Pretty much anything in the Liberal Guardian. Example: "The events took place at the notorious Corporate HQ, where evil and conservatism coagulate in the hallways."
The brainwashing minigame is always good for a laugh. Only a game like LCS would allow you to brainwash people by beating them with fists full of money, forcing them to play violent video games, or watch Bible Black.
One Boring, but Practical gameplay style can manage this - there come times when you want shut down a location to prevent something or spread non-violent political goals. Take practiced Liberals with Ninja Suit and cans of spray paint. Infiltrate a high security location, say a military base, police station, CIA/Ministry of Love, or Prison. Spray paint every single available wall without being detected and escape. Watch as they put off plans like assassinating the publishers of secret documents or raiding their location due to having to move after thoroughly graffiti-ed.
