Reuben here was right that Captain Britain has done jack-all for Britain since the first arc, the most she did in Britain or Earth’s defence was plug a problem her team helped cause (and even then she couldn’t help but sabotage the plan to fix it because of her entitlement over keeping the Captain Britain title). Betsy didn’t even give a proper defence against him, he was like “Krakoa has seized control of Avalon for themselves” and she was all “hey, we’re treating it alright, we love it like it were our own”, completely missing the point of his complaint. A smart book might have him use these as legitimate points to make his stance on mutants reasonable by comparison and recruit people to his cause like how real life hate groups do, maybe give Betsy some drama over how she felt she could have done better and how her actions might look to the outside world, but the book is staunchly against everything he says without actually doing anything to prove him wrong and firmly and uncritically in favour of everything Betsy has done even though we’ve seen ourselves over the prior 20 issues or so that he largely hit the nail on the head and everything she says in defence of herself is just driving it further into the coffin.

I know full well who’s got Excalibur (the sword) now. But the sword and the myth are too intertwined to ever be separate no matter who wields it now. The job of Captain Britain was even created by Merlyn himself, they’re all inextricably forever linked to Arthurian myth from the meta perspective. And until she was forced to give up the name of her team, she was pretty hellbent on keeping it. That’s not exactly textbook cultural appropriation since that’s too fantastical to be in any textbook, but I think it fits the bill of cultural appropriation well enough.
