In Norwegian, you "hit two flies in one swat". In English, you "kill two birds with one stone". That sounds so violent, like, whoa, hold on, I just wanted to swat some flies and you want to mash birds to a pulp with stones instead? That's kind of fucked up.
@thor England built a global empire with the sword and cannon! You think cannons are more than just throwing stones really fast?
Totes violent.
@thor in German we have the same as you in Norway: "Zwei Fliegen mit einer Klappe schlagen"
And here you can find it in many other languages...

@thor Only metaphorically though, you understand. 😎
