Meloni heads Italy’s most rightwing government since the second world war. Italy’s criminal code punishes with a fine ranging from €1,000 to €5,000 anyone who “publicly defames the republic”, which includes the government, parliament, the courts and the army.
If I had the money of a lead singer of international band I would consider a €5k fine a “campaign donation” to the other side and go call them fascist and get it in the papers.
