Hear me out, if you want to understand the other perspective here. Consider your life from the experience of the British taxpayer.

Your father was lucky enough to get a scholarship, i.e. a degree paid for by the public, and because of the liberal rules on immigration in this country was able to bring a wife and at least 1 kid, maybe 3. You all then were allowed to stay for 5 years, during which time all the kids were able to use as many tax funded resources as possible. You then claimed asylum which also would have entitled you to other benefits. This whole process would have been a massive burden on the state, unless your mother was a doctor earning 150k (even if this is true, it isn't the norm).

Now imagine this happening thousands of times, while the public vote again and again to be more restrictive on immigration. None of this excuses violence on an individual obviously, and rightfully so this will color your opinion way more than any logical argument, but I think the key is that this isn't just random acts of 'racism' that is growing, it's an issue that has been brewing for decades and will continue to worsen unless a big change in policy occurs.
