An African National Congress Member of Parliament has called for racists to be "blacklisted".
Jabulani Mahlangu made the call during a debate on racism in the National Assembly, which was requested by Freedom Front Plus MP Pieter Mulder.
Mahlangu reiterated the call for the criminalising of racism.
"We call for the establishment of a national register of racist offenders as part of tightening the legislation. We need to ensure that racists are blacklisted," he said.
He said the list of racists should be made available to embassies, so they might reject applications for visas and work permits.
"These racists must only remain here in South Africa so that we manage them so that when they are fine we can only then expose them to the rest of the world," he said.
Mulder said racism must be condemned by all.
He questioned the root of the university protests.
He said the current protests were mostly artificial.
Mulder said small numbers of activists were fuelling the violence in the universities.
Democratic Alliance MP Prof Belinda Bozzoli said it was not unexpected that racial hatred had emerged.
"The unstoppable force of increasing numbers of poor students has met the immovable object of the costs of running proper universities," she said.
Economic Freedom Fighters MP Thembinkosi Rawula said the violence of racism frowned on black dreams.
He said black people were not considered human by racists.
This, he said, was why it was normal for black people to earn up to six times less than their white counterparts.
United Democratic Movement MP Nqabayomzi Kwankwa said Afrikaans should not be forced on students.
