Free speech is often hard to live with but think what life would be like without it. It would be like life in a Soviet Bloc country or in the Third Reich. During Soviet times people who spoke too freely found themselves arrested, brutally interrogated, and sent into the forced labor camp system, which the great Russian dissident writer and prisoner (zek) Alexander Solzenitzen called the gulag archipelago. Most of the millions of victims didn't survive including the great Russian Jewish poet Osip Mandelshtam, who died of injuries and malnutrition in a transit camp. Everyone who openly opposed Hitler found themselves in a concentration camp where they were usually shot. These are extreme examples but I can't think of any cases of democratic countries which have some sort of modified free speech. Perhaps some countries are more polite in their speech than others, but I suspect they are countries which do not experience much internal or external political or social pressure or debate.
