> The UK is not weighting Asians higher than other non-white races.

I didn't say it was. I said that the upthread commenter’s use of “differential racism” to describe their explanation in which Britain was doing that was, contrary to the claim that it was redefining “racism”, a perfectly valid use of the term “racism”.

I've also said in every post in which I've argued that point that I think that what is actually happening involves nationalism in light of the HKs colonial history, not, or at least more decisively than, racism, differential or otherwise.

There two different issues here, one about whether a hypothetical scenario is within the usual definition of “racism” and one about whether than hypothetical is the best explanation of what is factually occurring.

The explanation is the obvious one. The UK has a treaty with China intended to prevent what is happening from happening. China is in breach of the treaty and, in light of that, the UK is acting to protect people to whom it believes it has an obligation. It has nothing to do with either racism or nationalism.

No one is arguing that point. What is being debated is why very conservative racists in the UK culture are overwhelmingly supportive of Asians over Syrians and North Africans. ...and differential racism is my belief as to why.

You are using “very conservative racists” and “differential racism” to explain something which is better explained by historical relationships and obligations. No such relationships or obligations exist with Syria or most of North Africa.

No country can invite everyone to immigrate. They have to be selective, and that doesn’t make them racist. No one has the right to immigrate to another country: it’s a privilege granted by the government and people of that country who make decisions about who to accept according to their own interests and perceived obligations - again, not racism.

So you’re starting from the presupposition that British conservatives are racist and then trying to explain away evidence contrary to that presupposition.
