If we are making subtle distinctions then your assertion that I did not provide an answer is exactly that, I did provide an answer sometime back, true I did not repeat it because you had not accepted my original answer, so there seemed little point in repeating it as you were clearly going to keep rejecting it.
The whole point (as far as I am concerned) is with nuance in terms of political messaging.
It is that those using such terms, in this case Donald Trump, do make 'labelled ' statements that for such as Trump passes for nuance. Politicians generally rely on nuance as an excuse for misunderstanding, by others, of what they have said, Boris is a past master of this. Politicians know that depending on however/whoever reports on their announcement it will be nuanced (positively or negatively) in the way its received, e.g. on what is perceived as 'biased' reporting on the BBC (and elsewhere)
I am not arguing that nuance is not subtle distinction, but that within the context of politics there is both negative and positive aspects and many politicians rely on this to, at best mislead, at worse be economical with the truth. The phrase "You might think that, but I can't possibly comment" springs to mind.
The example I gave was in terms of immigration. Politicians of all persuasions have relied on the nuance of this term to positively or negatively define not only the process but of those involved, sometimes not making and/or making the distinction between, legal or illegal immigrants; between asylum seekers and those seeking economic improvements in their lives, between (assumed poor) would be immigrants (mostly refugees) who are left behind in camps and those perceived to have money, who can pay people traffickers to smuggled them into a country. etc.
