Multiple European Union states are breaking with post-war liberal conventions and openly imprisoning prominent political opponents and intellectuals for ideological crimes.
The ideas and words which go against the political elite are "violent".
Nikos Michaloliakos, Golden Dawn’s General Secretary, was given 13 years for a RICO-style charge that alleged his patriotic Greek party, which until recently was the third most popular in the country, is a criminal organization.
Michaloliakos was not tied to any specific crime, but prosecutors used editions of his group’s magazine featuring articles about Germany during World War II from the 1980s and 90s to argue that their political ideas were a form of violence in and of themselves.
When the average person isn't even allowed to vote for the alternative to the current globalist politicians, then true violence is the only available option at the end.
