Freedom of speech ought to be interpreted as a value linked with different aims of a democratic society. It is not admissible to accept a freedom of speech which conceals harmful intentions against a single person or a social community. The historical defence of freedom of speech is based on the enlargement the debated of ideas, rather than on a subjective exercise of personal extravagance. To respect religious feelings and another personal aspects is an absolute limitation of freedom of speech. Because of that, we do not agree with the identification of Muslim religion with terrorism that has been published, trough Mahoma’s caricatures, in some European newspapers.
