I agree with everything up until you said “dilutes”. I would argue that immigrant cultures don’t dilute the host country’s culture, they add to it. In other words, the culture that was there still exists in the same amount and in the same “concentration”, and immigrants bring their culture to newly developing areas of the country/state.
Yeah, I read their about page. I wouldn’t trust them as a lone voice on something, but if other groups come to the same conclusion, sure. But mostly, I don’t trust articles with AI image headers. It makes it seem like the article is written by a bot.
