I am born and raised in England to Indian parents so always had some internal tension. Sometimes, I don't understand my patents culture and sometimes I don't understand English culture. However, I've realised I am who I am, and can take the best bits from both. There are some bits I don't like so I'm the better for being / having that mix. I married an Irish person who moved over several years ago. Irish used to be the "other" and were screwed over, but now are sometimes considered "white", so just shows the target moves.
There has always been racism in British society and unfortunately I have felt it pick up since the Brexit vote and Trump's election (I think it empowered them). However, it is from a small minority of people. In some areas it comes from ignorance, which I can kind of forgive. Others will always see us as outsiders with our foreign names (and my brown skin) no matter what we do. I just think, screw them. I mean, can they trace themselves back before the Normans, the Romans or the Vikings etc? Where do you draw the line exactly?!? England has always been a mix of people and culture so they're the ones missing out. I'm happy driving my Korean car to a German store to buy ingredients for a Thai green curry. Oh, I'll grab a French pastry for breakfast, Chilean wine for the weekend and well, you get the idea! Let's make the most of this multicultural place and ideas, and who cares about bigots who you can guarantee, like a cheeky korma and Belgian beer...
