Coming to this rather late, but I feel that NG should be allowed to go on QT.
Look at the experiences that we have seen in Germany in the last 20 years. There have been far right parties, far left parties who have won the "protest vote". At the moment it is the far left Die Linke Partei who are stronger.
Once they are in parliament they disappear in a haze of corruption and uselessness. They are not capable of governance, they can only manage populistic spoutings.
Haider in Austria was the same.
Let them have the microphone and let the people see how ridiculous they are.
