Life is cruel.

If those immigrant children can irrefutably prove they have no cultural, ethnic, family, or other identity ties, including but not limited to even knowing or being able to figure out that they are the children of immigrants, then they can stay.

Note this is impossible to do, because by proving this they disprove it, as they would need to know they are immigrant children to prove they have no other ties.

Whether it is cruel is irrelevant, it is whether they can be trusted. The evidence from muslim terrorism shows that cultural and religious muslims cannot be trusted.

It's fundamentally about who you value.

I don't think it is materially possible to value everyone on the planet, therefore the circle of concern must be smaller.

The actions of islamic terrorists shook my trust in cultural differences, but integration still seemed possible. Then the left went nuts and blm started their politically motivated ethnic hate and lie campaign, showing that discernable ethnic differences make integration impossible. Different british ethnicities might be, tautologically, different, but overlap enough such that they do not stand out as obvious outsiders. Integration here was possible, despite the cultural difference hate that some refuse to let go of.

I have been convinced by the actions and rhetoric of BLM and their supporters that visibly different ethnicities, that cannot become integrated and blend in a single generation simply by marrying a native, present an existential threat to those of other ethnicities simply by existing in the same nation.

Further to this, those with an internationalist circle of concern, i.e. who consider themselves citizens of the world, or European, over British can also fundamentally not be trusted.

Conflict in the future is something I believe is inevitable, and the outragous and despicable behaviour of some with different identity groupings to native British have, over the last 4/5 years, convinced me the risk of them acting as a 5th column at best, outright hostile forces in the same nation at worst, is not empty paranoia but already happening.
