Sickening but not surprising. Death and rape threats aimed at women for calling out literal Nazis is exactly the kind of cowardly, misogynistic intimidation that should get people locked up, not shrugged off as "online noise." If you're attracting that level of abuse, you don't ignore it, you investigate, charge where appropriate, and make platforms take responsibility for the channels being used to organise and incite.
The "internal communication error" excuse from police is pathetic. Allowing a neo-Nazi rally to go ahead under paperwork technicalities while people are threatened on camera shows a failure of judgment at the least, and maybe worse. If the state is serious about public safety it needs clearer rules on extremist symbols and speech, faster policing responses, and accountability for whoever signed the permit.
Good on the MPs for not backing down. Standing up to hate should not expose you to personal danger, and the system needs to stop letting these tiny violent groups punch above their weight by terrorising people online and in the street.
