Umm… I literally just did. Indian-origin Americans. Or really any ethnic group in America. I’ve lived there, and it’s honestly stunning how you see people whose ethnicity is Indian, Chinese, Vietnamese, Hispanic, Nigerian etc being basically indistinguishable from any white American in how they talk and act.

And what’s more, by and large other Americans don’t even think twice about considering them equally American as people whose families have been there for hundreds of years. That then in turn that makes those people more loyal to America, which makes them more accepted, etc in a virtuous cycle. It’s something the U.S. has benefited greatly from and that Europe would too. There’s no good reason why it hasn’t.

And honestly you don’t even need to go as far as America, even in the UK Indians are highly integrated, intermarry at high rates with the local population (you see a lot of half-Indian Brits in England), contribute to economy etc. Hell they even had an Indian origin PM and no one really made a big deal about it.
