For my nationality - multiple times in Germany (I’m English).
The worst was a university professor who knocked my grade down from a 1 to a 3. This was on a group project which it was not possible to judge individually, which was not language-based, and on which I had the most prior experience. One of the others from the group left after two months and destroyed all our work in a hissy fit - and she got a 1. Since this was a triple-weighted course, this grade made the difference between a 1st and a 2:1, which is important since I was planning on an academic career.
My nationality was the only characteristic that set me apart from the other students, and she also once showed us a film she had made, about Norther ireland. It was one of the worst documentaries I’d ever seen - it included amateur fraud such as using images from the 1970s, with soldiers standing on the streets, alongside subtitles and dialogue claiming this was happening today. I can only assume I lost the marks because I was British.
It still grates on me, obviously. One day when I’m rich I’m going to find that woman and ask her why she felt justified ruining someone’s life just because they were English.
For my sexuality - missed a promotion at work. Got reported to social services because my having a child didn’t fit in with my ‘lifestyle.’ Social services found that the school had no reason to report me whatsoever, they found numerous homophobic references in the report, and advised me to make a complaint against the school.
Have had violence threatened against me, catcalls, things thrown at me and so on, because I’m gay, but that’s not exactly ‘discrimination,’ and it hasn’t happened much. I’ve been fairly lucky, especially the last year or so.
I’ve seen people of African and Afro-Carribean heritage get preferential treatment where I work, but given that I also saw precisely the opposite happening before the new person started hiring, it’s understandable.
I’m living in England now and most of the time my sexuality is invisible, so I don’t think my experiences are equivalent to, say, British Asians or Africans. But it still happens.
