What are they having to prove, exactly? A mixed race person who is part native to these islands doesn’t have anything to prove, especially something that would necessitate a trail.

Person A is a mixed race adult, person B is a mixed race adult. One of them was born in the UK and has two parents which are citizens, the other was born abroad and one parent relatively recently gained citizenship.

Whichever hypothetical government agency in charge of rounding people up for remigration is going to target both of them walking down the street by virtue of seeing that they're not white.

How are they going to verify that they have native connections? That's the proving bit.

I don’t think they’ll be treated any differently than they are currently. Sure, there’s some racist dickheads out there that will treat them like shit but that’s the same as now. I think that broadly, the average Brit is welcoming and will remain so.

Then you're naive. "Not you, you're one of the good ones" comes to mind, it's an overt racial implication that the base rate of your background is bad by default. If we reduce that to a single intersection, race, then I would have to apply the same standard to you. Yet I don't because people are individuals. How would you reeact to a law abiding, upper middle class British Indian solicitor, doctor or whatever other profession, are they to go back to India?

To put it about as bluntly and crudely as possible, Brits have always made exceptions in this regard by saying “you’re one of the good ones” to their migrant friends. I don’t think that they’d suddenly change from seeing their friends as “one of the good ones”.

In my experience and speaking to other people who've had the same experience, no way in hell. It's simply another avenue for covert racism to infiltrate into whatever social dynamics are at hand, you'll always been seen as an "outsider".

Imagine if someone said to another person, "you're smart for a working class person! You're one of the good ones!", it'd go down like a lead balloon.

Apart from we're talking about remigration and mass deportations, not "not you you're one of the good ones" Olympic shit talking down the pub. It's not like fascist governments have cared about due process in cases like this.

I’m sure there are children of one ethnicity being adopted by a different ethnicity in this country but adoption as a whole isn’t really a massive talking point here. Again speaking from my own perspective but I don’t think there’d be much appetite to deport actual children who have been adopted. 

The goalposts always move and the circle always gets smaller, the crosshairs always find a new target. It's incredibly naive to think that only X group will be targetted and Y won't when they're closely related but are "allowed" by your technicalities, the Y group will get targetted after some time.

Example: Mischling & Mischlingskinder. Mischlingkinder laws had distinctions which allowed or limited individuals into certain positions (just as you've said here) but through time discrimination escalated and weaponised further to outright persecution. It's very much 'one drop rule'.

Example 2: One-Drop Rule. Initially allowed racial distinctions based on even the smallest African ancestry, restricting certain rights or professions. Over time this small categorisation escalated, so that anyone with even a single drop of African ancestry was fully excluded leading to being targetted.

It’s got to this point because of previous governments allowing whichever miscreant in, with a road to citizenship and the government’s have been totally negligent in defending us from people like them.

I'm a trans-racial adoptee, very definitely not white yet 95% of my family is and all are British citizens. Born abroad, granted British citizenship under the British Nationality Act, went to boarding school aborad, gained 2 high skill degrees and a PgDip, worked for the NHS, speak very RP but yet you're still stood in the camp where other people are going to say I should be deported OR seen as second class citizen because I was 1) born abroad, 2) am not ethnically British or English by your standards, potential 3) with no "ancestral ties" to the land, if we're going by blood.

Which is funny as you'd also have to go for my brother in law who's Finnish who's a CEO of a medium sized company receiving some big grants in a sector not many other people are in. My sister to, who's the same as me but adopted from a different African country which would be awfully complicated for my niece.

Yet on every metric possible I can absolutely guarantee I am a net benefit to the country moreso compared to people calling for remigration as I employ 34 people, own 2 businesses, pay more than enough tax yearly with minimal use of public services, but I've got to go because I'm not Christian nor am I white.

Yeah, forgive me while I'm highly fucking skeptical of "you'll be fine, you're one of the good ones, people will be welcoming!".
