Nazis are not people. They are lower than cockroaches. They are the punching bags of society and rightly deserve every bit of scorn, spew, and spite thrown in their fucking faces.
That said, if any protected groups get discriminated against, throw a report and the mods will take care of things.
If you really need to know a protected status: age, race, gender, religion, skin color, orientation, etc etc...
EDIT: Nazis advocate for the violent overthrow of govt and therefore get branded as 'terrorists' so yeah they have no human rights. :P
