I will preface this by saying that I am white and do not look like a minority. I am, however, Jewish. I have experienced anti-Semitism on a few occasions. Whenever I have spoken with friends about my experience, they have been surprised that this happened.
My childhood best friend (half Jamaican) was recently telling me about how she experienced racism on many occasions growing up in our predominantly white hometown . I am embarrassed to say that not once did I notice it happening.
I think it may be helpful to people who haven't witnessed or experienced acts of intolerance to hear actual stories of it happening. Even the little things.
My experiences are as follows:
My parents were teachers in our local high school. My high school was very big on "tolerence" and preached about the importance Holocaust, inviting in loads of speakers and organising trips to Auschwitz. My mom was the only Jewish teacher in the school and this was common knowledge, as she had given a few speeches in assemblies. It is also important to note that my brothers and I attended the school, so it was also common knowledge where we lived.
On one occasion, she gave a bad grade to one of her students who repeatedly didn't hand in his work. The student targeted our home for the next few months. We would receive phone calls in the middle of the night, playing traditional Jewish music. We would have crude drawings of "stereotypical" Jews in our mailbox. We had our house egged on many occasions, often with raw bacon left outside the front door. Though we weren't kosher and were very much secular, the intent was very clear. The student (who we knew was the perpetrator through other students at the school) never faced any consequences. We had no proof who was doing this to our family. But the feeling of being targeted due to our birth religion was so scary.
I now live in the East of England and while nothing has been personally targeted at me or my family, there have been many instances of graffitied swastikas on pathways and buildings. I have seen people talking about Jews being at fault for the Israel-Palestine conflict when protesting for a Free Palestine (which for the record, I am for, along with all the other Jewish people I know).
I figure if I am not even a visible minority and have experienced this, I can only begin to imagine the horrible things people of colour have learned to live with. Maybe if we talk about the incidents we have experienced, we can move forward more quickly.
