Perhaps you can enlighten us with an example of a European Socialist party that seized power illegally or refused to surrender power after losing an election. That is the true test of whether or not a party is acting within the political process. Most parties use inflammatory language and demonize their opponents. That is politics.
A lefties shooting a man with opposing views, after all the politicians brainwashed people Fortuyn was evil, is that free speech too?
Also very interesting is that the PvdA refuses to leave the offices they are required to leave. The LPF is entitled to that office space. But those democratic socialists won't leave, trying to fence off the LPF from being an effective party. Did I mention they still are using the national tv to cause as much damage to the LPF as they possibly can?
PS Knowingly spreading lies is slander, not free speech.
