Regarding this quote from Rick and Morty:
This seems like a good time for a drink, and a cold calculated speech with sinister overtones. A speech about politics, about order, brotherhood, power. But speeches are for campaigning. Now is the time for action.
Aren't political speeches supposed to be pleasant to the ears of the listeners? According to my understanding, the phrase "sinister overtones" means having a dark side to something. So why would he want a speech with sinister overtones?
