(Skip the monster below, if you want to get to the actual question.)
Sorry if I come off as anti English, but I often find the apologists for British imperialism as being insufferable, and I suspect that it's mostly Americans doing the apologistm. Even my school, which is mostly Mexican American, has people who aren't even white saying that British imperialism is a good thing because of free trade. And this was a response to saying if the Opium Wars were justified. I can only believe that this apologism is because of a common language that is shared. I often feel somewhat offended that a country that I believe is, or at least should be, more than just a daughter of English culture is often referred to as if it is just another Dominion in the British Commonwealth that British immigrants went to, while I feel that the many German, Irish,italian, polish, Russian, and now Mexican descended Americans are forgotten in favor of the Anglo Americans. I mean look at Wisconsin, I can't imagine it without the German influence. What about California? Even the South sees itself as not being descended from English culture but, being its own unique American culture, as can be seen in what ethnicity (White) Southerner's describe themselves as. Sorry for the long rant, but I can't help but describe my motives for asking these questions.
(Motive rant over)
So, what I am asking is if after the AWR, can American culture be less English oriented then how it is today. Like have German culture be a bigger influence on language and holidays, like having a lot of gratuitous German words in American vocabulary. What about a lot more Irish influence , so that the country can still speak English (somewhat) but is regarded in the same way of Ireland as the Anglosphere kind treats them like a red headed step child that's forgotten.
(Ex. People talk about Brexit causing English to no longer be an official language in the EU , but English speaking Ireland is still a member.)
Try having English names less common, while immigrant names from all over the world are more common, so as to make a difference between the similar names across the other English speaking countries.
Is it possible for early Americans to try not be obsessed with staying "racially pure" Anglo Saxons and instead be more accepting of mixing with other ethnicities? What about having immigrants less pressured to conform to standard Anglo American names ( I am aware that a lot of names are Hebrew in origin, but many see them as being British) Like Asians keeping their names making them acceptable for Americans and not seen as eternally foreign.
Also, try to change the view that American=white, so that non Americans recognize the US as being a nation of immigrants from across the world. Maybe showing Americans as being swarthy when compared to Englishmen in British propaganda.
I am getting tired and I pretty I have written too much for what will only get a few responses compared to the numerous Brit-wanks.
TLDR: Try to get American seen as so different from Britain that the British no longer refer to them as "Our American cousins". They have to speak English ,but the accents have to have influence from other languages in Europe and Asia due to immigrants with lots of foreign words that aren't French.
