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.
I mean in the case of the guillotine it literally is. St Just ended up guillotined himself, having sent hundreds of people to their deaths as one of the guillotine’s most zealous proponents.
