"something that could offend someone" thats too simplified.

You can freely express your opinions regarding any political party or head of state and so, but not directly and specifically offend them. You can say "their performance this year wasn't good due to that or this". But cant say "They should eat shit!" or "deserve to be shot" which kinda is also OK because the former doesn't contribute to anything and the latter we all agree is highly immoral or inhumane.

PS: I'm talking from the perspective of Germany, not entirely sure about other countries.
