The Italian government raided and arrested members of U.S operated website Stormfront. The arrest were not based on any real threat, but on the fact that the government discriminates against people with certain views.
The members arrested have been accused of compiling a list, or in other words listing people who they thought were active against the civil rights of the indigenous Italian people. They violated no law in making the list. The ADL has a list on people who they believe are enemies of the Jewish people, but no one is arresting them.
Whether you believe as a president (which I know you don't) that white people have rights, you could at least condemn these actions by Italy as a violation of freedom of speech and the right to associate.
