You might want to look more at why people are against the waves of illegal immigration and less on the color of their skin.
The governments of Europe no longer hold a monopoly of violence. Terror groups and MENAPT groups have brought a diverse range of violent threats to people.
Building a robot army to solve this is one viable solution that is hardware and software based.
The efficient & practical way is to stop renewing residence and work visas, making acquisition of visas harder through complex demands of high language proficiency, and a high amount of money as proof-of-funds, perhaps requiring a local referral too. It's what countries that don't want immigrants but don't want to say it out loud do.
As a philosophy of law point, aren't laws passed to make things illegal if they aren't wanted? Rather than legal?
"it's not that I don't like them - I am not like that, its just that I don't want illegal immigration"
BTW I don't disagree with the people who don't want everyone be welcome, I just think that their solution ideas and demands are misguided. My observation is that people from various ethnicities can function in cohesion and are about the same when they are from a similar educational background and rarely have ethnical or racial issues among themselves and IMHO all the problems will be resolved if you let people naturally find their appropriate group they belong to instead of having BS like country borders and visas and DEI or race based positive discrimination etc.
The worries people have, especially in somewhere like Britain, is it's a country with a relatively small population compared to the level of immigration, and housing is an enormous problem. One outcome that I think can be to a considerable extent[0] attributed to high net immigration is that housing has become smaller (many houses divided into flats), and housing has become much more expensive. So anyone who already owned a house is sitting fairly pretty, as they get bouyed up by the housing market, but anyone looking to buy for the first time, or buy into a new market for the first time (e.g. moving to near schools for kids) is going to have a massive problem, as the competitive pressure has up-bidded housing and made it worthwhile to subdivide and sell/rent smaller dwellings.
This could be all white people doing it (somewhere like Cornwall in the UK is mostly annoyed because other Brits buy holiday homes there, driving up prices for locals and their kids who are coming up) - it doesn't matter. The housing costs are what matter. And they, a bit like fuel, drive up everything else: NHS workers need higher salaries to just be able to live in many places, which drives up taxes.
This isn't to avoid actual race/ethnicity-related tensions. But there's a giant clump of people who are just fed up with their money going far less far than their parents' and grandparents' money did when it comes to one of the fundamentals of life: housing yourself and your family. And their parents and grandparents are equally upset that their kids/grandkids have in a major sense a harder life than they did.
[0] definitely not fully; there are multiple factors. But if you net import the equivalent of the population of Liverpool each year, and you aren't building a Liverpool each your to house them, it's obvious that prices will start shooting up.

Basically economic migrants - predominately young men from the middle east - disguising themselves as Refugees and taking social supports away from the families fleeing warzones.
In other words, this is actually welfare fraud that happens to have a travel component.
Home break-ins can be avoided by abolishing locks on your front door and leaving them open for the public. You go first please.
The question was simple, why do you support illegal immigration in a country's borders as being OK, but not crossing in the borders of your house?
It's easy to be virtuous and generous with other people's money/resources.
I think we are done here since I don't feel spending time for positions I never claimed. I despise this type of argumentation, its a known fallacy and its useless.
You can count yourself as won an arguments if you feel like that.
It's the same reason we don't seek to improve crime rates by legalising theft. Sure, there'd be fewer people labelled as "criminal", but the original problem would remain (and in all probability would become worse).
Obviously, it is the reason that matters and the reason is not benign.
People want other people to like people in certain way they and then castrate Alan Turing for illegal love. People want to have slaves then they have illegally free slaves problem.
Why pretend that this is about upholding the law?
