No, not OK.

Even if we admit the criminalization of insults among private individuals, what makes it pernicious to criminalize insulting politicians is that they are powerful.

Politicians, as a class, effectively control mass media, state violence, and the purse. One of the only effective curbs on their power is ridicule.

In America this is called punching up.

Pray tell me, would you be OK if a EU police arrested a comedian for mocking [1] Putin or Trump? If not, your position is strictly partisan therefore not universal, and therefore self serving.

Anyway, we found the EUist.

[1] I said mocking, not encouraging violence
