As Donald Trump has become a major force in American politics, behind him a new conservative movement has been growing in strength and prominence.

The alt-right, or alternative right, is an umbrella term for a group of Americans who share a desire to eschew political correctness, are hell bent on breaking the current political system and are viewed by critics as racist and dangerous.

The prospect of the alt-right's survival — even if the Republican presidential nominee Mr Trump loses the election — has alarmed traditional conservatives, as the movement threatens to tear the Grand Old Party in two.

Milo Yiannopoulos is a young, gay, British darling of America's alt-right and a senior editor at Breitbart, a conservative American news website that is challenging the dominance of traditional media outlets like Fox News.

"It doesn't really matter if Trump wins or loses because this movement isn't going anywhere," he said.

"Whatever you read into the polls it is at least 30 per cent of the American population who are sick of the establishment, sick of globalism, sick of the media elite, sick of the political elite, and probably a lot more than that frankly — people who just don't want to vote Trump but agree with that basic premise."

Yiannopoulos gained a cult following at Breitbart for penning op-eds criticising feminism, transgender people and Islam.

He has written articles calling women's liberation "probably a mistake", driven by the advent of the pill and the washing machine.

"In the case of transgender, it is elevating a mental illness to the status to some kind of civil rights struggle, which I find bizarre," he said.

"Feminists deserve it because they have been man-hating and miserable and horrible people for decades now and women agree with me."

The infamous 33-year-old and his entourage are in the middle of a national speaking tour, visiting college campuses across the country.

He speaks to sell-out crowds and draws thousands of viewers to his live streamed events.

Western countries 'are the best countries in the world'

He calls Mr Trump "daddy" and has been labelled the "face of the alt-right", but he said he just happens to know the movement best.

"My experience of the alt-right, with its concerns about immigration and trade and all the rest of it, is that they are not concerned with white identity per se, it is more about preserving Western civilisation," he said.

"They want the countries in the West, which are the best countries in the world, to stay strong and to stay free, and if you have massive influxes of Islamic immigration there is a risk that will not be the case in a couple of generations' time."

Yiannopoulos has consistently advocated for the importance of trolls — people who start arguments on the internet — and he was permanently banned from Twitter in July for calling Ghostbusters actress Leslie Jones a "black dude".

But the alt-right's favourite son is unapologetic.

"I prefer to think of myself as somebody who will go there and say what other people are thinking because nobody else will," he said.

"And some people you know cry foul and pretend to be offended because we now live in a society where grievance and victimhood is being elevated into a sort of currency that means something, that it is worth something — but it is not."

'It is about loving your own people'

White nationalist leader Matthew Heimbach hosts a live daily podcast from rural southern Indiana.

The founder of the Traditionalist Worker Party is against globalism and believes that white working middle class has been disenfranchised.

He said his audience numbers in the tens of thousands.

"I am a white nationalist, I care about my people, I'm bonded together by blood, culture and heritage, and shared destiny," he said.

He is only 25-years old but has been labelled a fascist, the new face of racism in America, and the next David Duke — the former grand wizard of the Ku Klux Klan.

"I think that every group of people should be able to advocate for their heritage and their culture and for their future, so what is being called racist is self-preservation," he said.

"It is about loving your own people and your own culture."

Mr Trump is popular in rural Indiana.

The relationship between rural Americans and a billionaire businessman from New York might seem unlikely, but his "America first" message resonates in a place where many in the white working class people see a bleak future for them and their children.

White nationalist political party wants to 'fight for a better future'

Matt Parrott, a member of the Traditionalist Workers Party, said the alt-right movement resonates for young white men who feel a sense of humiliation.

"The statistical reality is young Americans are running out of options and are being pointed and laughed at by the entire world," he said.

"Because they are told because you are white and privileged, you are going to have a very privileged life, and these young men are coming out into the world and their parents are kind of pointing and laughing at you, you know, why aren't you succeeding like we did?"

The political party Mr Heimbach founded currently boasts only 500 members, but in 2018 wants to be fielding candidates in local and state races.

The white nationalist movement in America is disparate but Mr Heimbach is embarking on something that has not been done before — an effort to bring together all nationalist groups to form a united political front.

"There are already hundreds of thousands of active white nationalist members of the alt-right in the United States, millions of people who agree with us as we've seen with the vote for Donald Trump," he said.

"So what we are going to have to do [is] unite those people, organise those people, and mobilise those people.

"We are here to be able to be that vanguard, that spearhead but we are looking to be able to work with all nationalists to be able to fight for a better future."
