It should be a no brainer that being unable to insult politicians is against democratic freedom and anyone joining politics should be ready for it.

You can't criticize your worthless sell out politicians? Well tell them I told them they are a bunch of cunts failing the country and they will throw the country into the arms of fascists, and that they should do the world a favor and end their worthless fucking lives.

Unless the politicians are israeli politcians

there is no special law prohibiting the insulting of politicians. it is illegal to insult any people, period.
