I believe if everyone who was against the current oligarchy started placing guillotine stickers everywhere, like you might for a favorite band, people would feel less isolated in their distaste for the current system.
And in an ideal world those who the guillotines are for might realize just how much they are in the minority.
Exactly, people fantasise the idea of quickly disposing of political enemies (for a higher goal, of course) but never really read about what that leads to.
Once you normalise killing people who are the wrong people, guess what happens.
