Should Golden Dawn, Jobbik, the NPD and other such neonazi parties be banned

[DavidB.]

Yes, these three parties should definitely be banned. However, it is hard to say at what point parties cross the (thin) line.

I basically agree with this. The other issue is, why is it not OK to discriminate based on race and ethnicity but OK to discriminate based on, say, gender, sexual orientation or gender identity or socioeconomic class?

If a party holds that all women, all transgenders, all bisexuals, or all working-class people need to be deported to concentration camps, then banning it would be a good idea as well.
