Freedom of expression is a big deal in Sweden. Tryckfrihetsförordningen (the other constitutional part besides Yttrandefrihetsgrundlagen) dates back to 1766. It's the oldest law ensuring freedom of the press and freedom of expression. Heja Sverige!
Freedom of expression is actually relatively limited in Sweden, but freedom of the press is almost absurdly well protected. It's more about ensuring the dynamics between institutions than the liberties of individuals.
I was curious about this so found https://www.riksdagen.se/en/how-the-riksdag-works/democracy/...
In it they write: "In Sweden, you have the right to have an opinion on anything and say almost anything you want. You have the right to express yourself freely on the radio, TV and the Internet. The Fundamental Law on Freedom of Expression sets out these rights. It also describes what is not permitted, for example defaming or publicly insulting another person."
Being prevented from publicly insulting another person seems not only silly in principle, but impracticable.
