I think the people you're after is the Spanish or Portuguese.... those languages you mentioned are prevalent in South America and the British didn't go there all that often and not usually to colonise. What you've done is confused a bunch of Europeans with each other and done so paying little heed to individual cultural heritages. As it happens the Spanish and Portuguese were all about exporting Catholicism and teaching folks how to do the bible..... meanwhile we Brits had set up the church of England in the 1530s and were doing our own thing. That's why the Spanish tried to intermarry into our royal family in the 1550s and then sent an invasion force in 1588. We are not culturally the same people.... not even a little bit. Though, tbf, we've had zero beef with the Portuguese for 900 years.
Suggesting all white people look the same and have the same cultural background is racism.... at least that's what I would say if I played identity politics but I don't. There are things about Spanish culture I enjoy... having a nap in the afternoon and things I don't enjoy, fighting animals for sport. I'm sure they love our TV but hate warm beer.
And no, I didn't say I was the victim - what I said was that cultural appropriation is reductive term used to leverage power. The British have been historical victims, we were invaded by the Normans (a branch of the vikings) the Roman Empire and some would argue more recently by the influx of other European states via the EU. As it happens I don't agree, I think there's great benefit to sharing the cultural landscape and the best bits of each culture can become a smorgasbord (another imported word) of the value of human life. This is best summed up by the Life of Brian skit - 'what have the romans ever done for us?'
After reading your work yesterday, in which I agreed with the conclusions you made about feminism and how people utilise their own outflanking manoeuvres to gain power in the conversation, I think you're now doing the same thing with nationalism. You've decided I'm 'a coloniser' because i'm part of an out-group, not because it's historically accurate or you even know where my heritage is from (other than I'm British). The pattern of in-group and out-group thinking is what sets up the pre-conditions for misery, that's as true for national identity as it is for gender identity.
You're welcome to continue using the internet and my language btw. :o)
