You aren't 'british' lmao. Canada isn't an ethnostate centered around one ethnicity. Although we have original native peoples that doesn't conflict with me being Canadian or not. Your situation is like this. A Chinese person could be born in Somalia and speak fluently but I have more of a claim despite never stepping foot there and having kindergarten comprehension of it.I know you are young but read what I wrote before carefully.
Also your entire post is contradictory. According to
what you wrote we are both not native? Unless only a white counts as native to you
