This issue of Diplomaatia is dedicated to one of the bulwarks of free and democratic societies – freedom of speech. There are various restrictions to free speech not just in authoritarian societies, but also in free or semi-free societies where there is no ubiquitous censorship or no official censorship at all. This issue focuses on some aspects of those limitations, e.g. problems stemming from the development of the Internet and taboos surrounding the concept of the sacred. We take a look at the situation of free expression in some European countries where that freedom is curtailed in more or less conventional ways.
