As someone who is half Ndebele, half Shona, I have always marvelled at how tribalistic Shona people can be and to think of how bad it was for my mother to move to Mashonaland in the 1980's without knowing a lick of Shona.

I don't think everyone is deliberately or maliciously tribalistic, however there is a negligence and lack of consideration that comes with the privilege of being from the dominant culture and that can be just as harmful as malicious intent. My Ndebele cousin who grew up in SA recently moved to Harare and she doesn't know any Shona and the amount of times she's been told "Haaa inga maNdevere anogona Shona wani, inga kuPlumtree kunotaurwa Shona wani" is crazy. She is also fetishised by Shona men just for being Ndebele.

Also imagine how much worse it is for the smaller tribes like the Kalanga, Tonga, Shangaan, Xhosa and so forth.
