I see your argument, but the Irish will absolutely throw hands if you call them Brits. They thing the term should only apply to people on the isle of Britain, not the British isles as a whole.

On a linguistic level yes. The ancient Greeks named the islands after the Prythonic tribes, who were active in Britannia and Hibernia (Ireland).

On a don’t-annoy-the-alarm-clock-aficionados level, nope. This guy isn’t with me. Never met them.

We’ll, they were Brits at the time, but I guess their time in the union was not entirely to their satisfaction.

Not really. British are from Great Britain (the island).

Ireland is not part of the British Isles
