For better or worse. Sweden has not been in a war since 1815, but some conflicts should come up in the open to get solved, and they don't because "someone might feel sad".
The real Swedish insults are sneaky and anonymous, in order to hide the insulter's identity back into the group. Written notes or graffitti in public places are such insults. An example could be a well seen written sign at a workplace saying; "Carl's mom doesn't work here" (meaning that that person is not doing his chores at the workplace, see Den som inte tar bort luddet ska dö! by David Batra).
