Why were teachers at Bodibeng High reluctant to talk about politics in the 1970s?

Teachers at Bodibeng High were reluctant to talk about politics in the 1970s because of the oppressive political climate in South Africa at the time. The apartheid government heavily censored and controlled discussions about politics, and teachers risked facing repercussions or even losing their jobs if they were perceived as being critical of the government. Additionally, discussing politics could have been seen as inciting rebellion or promoting anti-government sentiments, which could have put the school and its staff in danger. Therefore, teachers at Bodibeng High likely avoided discussing politics in order to protect themselves and the school from potential consequences.

The provided context does not mention Bodibeng High or teachers' reluctance to talk about politics in the 1970s. So I cannot answer this question from the provided context.
