American race-faker Rachel Dolezal has returned to the limelight with her first ever visit to Africa on a lecture tour about race – a move which has been met with outrage, calls for a boycott and a string of scathing memes.

Police flanked Ms Dolezal's first key note event after a hostile meeting with mostly black students who objected to her insistence that she had 'an authentic black identity' despite admitting to being 'biologically white'.

The 39-year-old, who was labeled an 'ethnic fraud' after passing herself off as a black woman for more than a decade, recently took a Nigerian name to make herself sound more authentic.

The shamed black activist, who now calls herself Nkechi Amare Diallo, outraged her young black audience in Johannesburg after equating her claim to being 'trans-black' with the trans-gender experience of Caitlyn Jenner.

Shock: The activist, who now goes by Nkechi Amare Diallo, outraged her young black audience after equating her claim to being 'trans-black' with the trans-gender experience of Caitlyn Jenner

Defence: Her host, Bishop Clyde Ramalaine, left, backed Ms Dolezal's right to compare herself with transgender Caitlyn Jenner

'I still identify as black… maybe trans-black is a good compromise because it identifies that I was born to white parents but have an authentic black identity,' she insisted as students of the University of Johannesburg tutted loudly and shook their heads in disbelief.

The mother of three, who has been forced to make ends meet by braiding hair after failing to get work since she was 'outed' as white woman two years ago, was invited to South Africa by a retired black bishop who wholeheartedly supports her extraordinary claims.

Clyde Ramalaine told MailOnline he backed Ms Dolezal's right to compare herself with transgender Caitlyn Jenner, who won Olympic glory when she was still known as Bruce, and argued there was an unfairness in the way the two had been treated.

'I find it amazing that Bruce Jenner can be celebrated on the cover of Vanity Fair magazine and yet no one has ever said to him 'but you deceived people all those years, you were in a male locker room, you slept with women',' he said.

Pariah: Dolezal's speech, during which her audience tutted and shook their heads, was also ridiculed online in a series of damning memes

Ridiculed: One member of the audience in Johannesburg mocked Ms Dolezal by saying 'only a white person could claim blackness and tour the world talking to blacks about blackness'

Anger: Another audience member asked her what her daily experiences as a black person were, adding: 'Is it wearing braids, what is it?'

The former priest, who still styles himself Bishop, is managing director of Tsiloab Hoaldings, the communications company that organised the event.

He went on: 'No one accuses Bruce Jenner of living a lie, or calls him a fraud. He is celebrated for his bravery in being truthful about his true identity.

'Yet Rachel is vilified, is treated as a pariah, accused of lying about who she really was.'

'She has chosen to self define and that's her right. Can't we just live with who she wants to be? I embrace Rachel as she defines herself,' he insisted.

The mother of three was unmasked two years ago as a white woman after building a successful career as an advocate for black issues, based on wild exaggerations about her background.

Despite being exposed as a fraud, Ms Dolezal was invited to the inaugural Quest for Non Racial South African Society Dialogue in Johannesburg.

Aspiration: In her new book, In Full Color, Dolezal confesses to not meeting a black person until she was ten and began fantasising about being black after reading National Geographic

Tension: Ms Dolezal's arrival in South Africa comes at a time when the country is facing its most serious political and economic crisis since the end of apartheid in 1994

Deriding Ms Dolezal's claim to 'racial fludity', she was told by a member of the mostly-black audience of students that , 'Only a white person could claim blackness and tour the world talking to blacks about blackness.'

Another attendee demanded to know, 'What are your daily experiences as a black person? Is it wearing braids, what is it?

Ms Dolezal's arrival in South Africa comes at a time when the country is facing its most serious political and economic crisis since the end of apartheid in 1994.

The country remains deeply divided along racial lines and the arrival of a foreign white woman who claims a right to blackness has prompted shock and anger.

In her new book, In Full Color, she confesses she did not meet a black person until she was ten and began fantasising about being black after reading National Geographic and Sports Illustrated magazines.

But Bishop Ramalaine dismissed his friend's critics, claiming 'Rachel has proved that their blackness can be invaded and they are uncomfortable with that.'

Lebo Ramafoko, the head of the Soul City Institute for Social Justice, who has used her social media accounts to denounce the American, dismissed Ms Dolezal as 'a fake and a fraud who is just an ordinary white woman'.

Support: Dolezal, who has been forced to make ends meet by braiding hair, was invited to South Africa by a retired black bishop who wholeheartedly supports her extraordinary claims

'She is just sick or a fraud. Can you imagine a black person from Africa being given a visa and this special treatment to go to America or to London claiming to be white and having the red carpet rolled out for them?

'This is just another example of white supremacy, why must we have to listen to her?'

Marion Stevens, a white feminist whose organisation supports transgender women in South Africa was appalled that Ms Dolezal was using the issue to underpin her arguments.

'If she is going to use transgenderism to back up her notion of trans-racialism, she is barking up the wrong planet.

'It is audacious of her to come to South Africa where she has no appreciation of our history to perform black feminism. Having her here is the last thing we need.'
