The one thing you seem to be missing in your anticolonialist tirades is the fact that Tristan was uninhabited. It’s not like native peoples were displaced by the British colonists, right?
Many self-described anticolonialists forget that "self-determination" doesn't actually mean "people who live far away from the mainland should just fuck off and take care of themselves".
I've experienced it a bit as a Frenchman (and we have quite a few remote territories as well) who has lived on a couple of remote places (that were uninhabited as well before becoming French, but that shouldn't actually matter) and it's incredible how puny, short-sighted and simply egoistical some people can be.
I'm saying that it is common for some people to advocate for jettisoning other parts of their country, especially if they are far away from where they live.
No, you're correct Britain is a collection of islands in the northern hemisphere. This however is an island in the Atlantic ocean and is a British Overseas Territory.
