Um, no? What harm does it do for people to label their ideologies and organize themselves based on those ideologies? Is a white supremacist any less terrible if they call themself a "white pride advocate" than if they identify with the BNP or Jobbiks? If they are violent, arrest them for the violence. If they call for attacking a group of people, arrest them for that. But don't ban their party.
Whereas you simply call for the supporters of these parties to be 'destroyed'. How very democratic of you.
