“[We] condemn racism, racial superiority and any attempts to polarise our campus community in the strongest possible terms,” Viljoen said.

He said the posters were placed on the university’s campus without the university’s knowledge.

Reports surfaced on social media that the university’s JS Gericke library approved the meeting, but Viljoen said the library only received a “query” about the meeting and no official booking was made.

“At this stage the origin of the posters are still unknown, but the University is currently following up on information received about the organisers,” he said.

On social media, South Africans and students criticised the university for the posters.

Electronic music duo the Kiffness said: “ When you’re photoshopping skills are on fleek but you’re also a Nazi at Stellenbosch University.”

Student Khadija Omar Bawa said: “This university is already made and breads Afrikaaner-dom, white supremacy and racial segregation.”“White Afrikaans “allies” hold your own accountable. Time to shine,” she added.

TeeKay Khumalo (@Royal_Khumalo) called it “just another normal day at stellenbosch university”.
