It is not against the law (not even Italian law) to write what you wish to have shown in public.
Article 10 of The European Convention on Human Rights.
1) Everyone has the right to freedom of expression.
This right shall include freedom to hold opinions and
to receive and impart information and
interference by public authority and
regardless of frontiers.
This article shall not prevent States from requiring the licensing of broadcasting, television or cinema enterprises.
2) The exercise of these freedoms, since it carries with it:
may be subject to such:
as are prescribed by law and are necessary in a democratic society, in the interests of:
territorial integrity or
for the prevention of disorder or crime,
for the protection of health or morals,
for the protection of the reputation or the rights of others,
for preventing the disclosure of information received in confidence, or
for maintaining the authority and impartiality of the judiciary.
The Italian problem is that you need to apply to the governmnt for permission to post any blogs. Something called the: "stampa clandestina"
You have been warned.
