We do not talk a ban of any far right group, we do talk about the ban of a
Nazi party. And the guilt of Nazi ideology is so much beyond all doubt as something in this world can be beyond doubt, This thinking of hate, racism and supremacism is responsible for the death of dozens of millions.
So,
morally there is absolutely no alternative to ban it.
One must ban it. Doing so is not limiting freedom and democracy - it is ensuring the protection of freedom and democracy.
Those of you making absolute claims about total freedom turning into total tyranny by banning Nazism (hey, I am reaching my beloved Popperian tolerance paradoxon again!
) , consider whether your forefathers have given their lives in defence of freedom given to Nazism so that it can sow its seed and have a richer and richer harvest every year (Nazism is on the rise), or whether they went to war for achieving the destruction of Nazism. When hearing comments like "banning a party means clashing with the ideals of democracy", then I think some hundred thousand British and American soldiers must turn in their graves in France, Italy, Germany, North Africa. I admit my tolerance for different opinions has found its limits here.
Beside the moral position, there is the pragmatical one. A group in hiding will just reorganise and form a new organisation under a new name, most likely. A ban will not disrupt the stream of new recruits Nazis are getting due to the social erosion in many areas of Germany, and Europe. So, a ban at least is unlikely to do any damage, and will probably not cause more concerns for the intel community tracking them, then they do right now.
An earlier attempt to ban them has failed, some years ago, due to police having infiltrators and informants in the organisation, which made the court slamming any evidence for the Nazis' anti-constitutional ambition over concerns that such evidence could have been fabricated by the police, and placed by it. It is said that this time this risk doe snot exist and that there are no informants. Which makes me wonder how the police then has done its work in recent years.
Nazism sucks. Any supremacist, racist, totalitarian ideology sucks, no matter how it is named. WWII costed 60 million people their lives. Nazi racism and megalomania established a terror and an industrialized automatization of horror that forbids any tolerance for Nazism to give it room for breathing and living. In the US, people get the death sentence for lesser crimes.
Zero tolerance for Nazism. Just this. What'S so difficult to understand in that? I would contradict myself if I slam religious fanatism, Muhammedanism, Stalinism or Maoism - but save Nazism from it. It all is totalitarianism par excellence.
