I'd take that even further, claims of intimidation are racist horseshit. For non-Antipodeans, the Kiwis hold a haka during rugby games. Those MPs know fucking well what a haka is, and it's not a threat.
NZ was founded on a treaty with it's indigenous peoples. Claiming their culture as intimidation is racism disguised by cowardice, and everyone involved knows that.
They weren't 'letting hell loose', they were performing an appropriate protest. This is racist BS.
