Mr Cottrell believes Australia should only accept skilled migrants, and has advocated for the country taking all the white farmers from South Africa and halting immigration from the rest of the world.

Like Mr Cottrell, Canadian alt-right speakers Lauren Southern and Stefan Molyneux fear the spread of foreign ideologies taking over the West. They’ve stirred up conversations around freedom of speech in New Zealand after arriving in the country last week to speak at an event.

Australia and New Zealand both appear divided on whether alt-right speakers should be allowed to express their opinions. Whereas some argue that alt-right speakers whip up hatred towards minorities, others say these speakers should have the right to express their views.

"Muslims can no doubt be decent and noble people, just as tame wolves do exist, but the fact is that Islam the religion is by its nature dangerous to the West," says Ms Southern in her self-published book Barbarians: How the Baby Boomers, Immigration, and Islam Screwed My Generation.

According to the pseudoscience Mr Molyneux teaches, white people are ranked higher than the likes of black people, Arabs and Latinos. He believes race strongly influences IQ, and IQ strongly influences how economically successful or criminally violent a person will be.

While these views may seem out of touch in a country like New Zealand that prides itself on being diverse and advocates for equality, the country has been divided over whether Ms Southern and Mr Molyneux should be allowed to express their alt-right views to the public, following the cancellation of their speaking event.

Auckland Mayor Phil Goff said the pair weren't welcome in any council-owned venues in Auckland because of their history of racism and intolerance. They were scheduled to speak at Auckland’s PowerStation last Friday, but the venue's owners cancelled the event at the last minute.

After Ms Southern and Mr Molyneux's event was cancelled, the pair took to YouTube to declare New Zealand hostile to free speech. Prime Minister Jacinda Ardern responded to that accusation on Saturday, saying New Zealand wasn't "hostile" to free speech - just to their views.

But Ms Southern hit back at Ms Ardern, accusing her of supporting multiculturalism and advocating for freedom and liberty, but then denying her and Mr Molyneux the right to express their unique views, regardless of whether it might offend some people.
