Terrorists in our midst

Can anyone tell me why the Australian Nationalist Movement (ANM) hasn't been outlawed under the anti-terrorism legislation?  Surely these guys' sole purpose is to spread terror.  They must qualify.  So why haven't all their possessions been confiscated and the members all locked up?  If someone even a bit foreign-looking so much as thinks about visiting a terrorist country these days they're on ASIO's watch-list.  So why haven't the ANM morons been woken up at 3am to be led away in handcuffs?  It couldn't be because they're white supremacists, and therefore just a few louts mucking around, could it?  I hope not.
