We should call Trump for what he is. A Proto- Fascist.

We sometimes forget that at the same time (1964) as Nelson Mandela was condemned them to life imprisonment. there were still] states in rge USA opposing segregation legislation which sought to end America own version of Apartheid in the South.

In the summer of 1964, civil rights groups brought almost 1,000 activists to Mississippi.^[83] Most of them were white college students.^[84]p. 66 Their goals were to work together with black activists to register voters, and to teach summer school to black children in "Freedom Schools." They also wanted to help create the Mississippi Freedom Democratic Party (MFDP). At the time, only white people could take part in the Mississippi Democratic Party. The MFDP was planned as another political party that would allow black and white Democrats to take part in politics.^[83]

Many white Mississippians were angry that people from other states were coming in and trying to change their society. Government workers, police, the Ku Klux Klan, and other racist whites used many strategies to attack the activists and black people who were trying to register to vote. The Freedom Summer project lasted for ten weeks. During that time, 1,062 activists were arrested; 80 were beaten; and 4 were killed. Three black Mississippians were murdered because they supported civil rights. Thirty-seven churches, and thirty black homes or businesses, were bombed or burned.^[84]
On June 21, 1964, three Freedom Summer activists disappeared. Weeks later, their bodies were found. They had been murdered by members of the local Ku Klux Klan - including some who were also police in the Neshoba County sheriff's department.^[83] When people were searching for their bodies in local swamps and rivers, they found the bodies of a 14-year-old boy and seven other men who also seemed to have been murdered at some time.^[85]
During Freedom Summer, activists set up at least 30 Freedom Schools, and taught about 3,500 students.^[86] The students included children, adults, and the elderly. The schools taught about many things, like black history; civil rights; politics; the freedom movement; and the basic reading and writing skills needed to vote.^[87]
Also during the summer, about 17,000 black Mississippians tried to register to vote. Only 1,600 were able to. However, more than 80,000 joined the Mississippi Freedom Democratic Party (MFDP). This 
 This showed that they wanted to vote and take part in politics, not just let white people do it for them

Despite the Civil Rights Acts such attitudes still persist in the US today but arguably we have never seen an actively racist president in our lifetime.

As the Guardian reports

Donald Trump heads to Capitol Hill on Tuesday afternoon facing an extraordinary backlash from his own party – and the American public – over his policy of separating children from their parents at the southern US border.

The separations occur when, under a “zero tolerance” immigration policy, adults are arrested for crossing the border illegally. As children cannot be held in an adult jail, they are held separately.
According to a Quinnipiac University national poll, two in three voters oppose the separations. Outcry from Democratic and Republican politicians, former first ladies, churches, commentators and business leaders is gathering momentum.
The president, however, seems determined only to up the ante. On Tuesday morning he tweeted that Democrats want undocumented migrants “to pour into and infest our country”. In a lunchtime speech to the National Federation of Independent Business (NFIB), he said the US had two options: “Totally open borders or criminal prosecution for lawbreaking.”
Tim Malloy, assistant director of the Quinnipiac poll, asked: “When does public opinion become a demand that politicians just can’t ignore? Two-thirds of American voters oppose the family separation policy at our borders. Neither quotes from the Bible nor get-tough talk can soften the images of crying children nor reverse the pain so many Americans feel.”
Trump’s campaign was built around a tough stance on immigration, with “build the wall” a frequent chant at his rallies. He is now losing the battle for public opinion, though support among his base is resilient.
For example, Republicans support the zero tolerance policy at the border by 55% to 35%, the Quinnipiac survey found. And while national voters oppose building a wall on the border with Mexico by 58% to 39%, three in four Republicans back it.

Trump's racist policy also give comfort to other here on Europe

Italian Interior Minister Matteo Salvini of Italy's far-right League

   has announced plans for a census of the Roma community. While those deemed to be foreign could be deported, he said, Italian Roma would "unfortunately" be allowed to stay.

We cannot also ignore Brexit has given comfort to Racist  in these islands and the  dangers that this brings.

As the Far Right take over the White house there are those who say we  are wrong to accuse him of being a fascist, but I think we should call it now before it is to late.
