Have you ever suffered any form of discrimination because of your ethnic group? What was it and how did you handle it?

I personally experienced tribalism from my university lecturer. He had issues because I had not chosen him to supervise my masters thesis. I chose a professor who lived with a disability and from my tribe, but tribe had nothing to do with it.
Anyways this other lecturer frustrated me, frustrated my efforts as a student in that department. One time during elections in Kenya in 2017, he told me in Swahili, “You Kikuyus will know that the world is round.” (What goes around comes back around). That is why he had closed his office door while I was inside. He said it behind closed doors. I was too naive to imagine that I should be recording a conversation with one who is supposed to be my mentor?
That threat was the beginning of my university confusion… I ended up finishing my masters degree in 5 years instead of the original 2 years. If only I had support from him as head of department I would have done much better.
I remember one time he asked why I was getting a passport document, he said in Swahili to me again in the parking lot, “You Kikuyus are wondering where you will run away to?”
That broke me. I never returned to his office for assistance ever again!
The Rwanda Genocide should be an example enough surely!
