Political activist Pieter Kriel says he does not agree with the views of Afrikaners who have moved to the US to be resettled.
Forty-nine Afrikaners have already arrived in the US after President Donald Trump signed an executive order saying they were victims of racial discrimination.
More Afrikaners are expected to join the 49 who are already in America.
About 70 000 South Africans have expressed interest in moving to the US.
Kriel says they will not be able to protect the Afrikaans culture.
