And yes I do think that there is a level of Anglophobia that stretches back in this country to the Revolution.
Overstating the case. More like going back to election day 1960. (As the tipping point when people went from being proud of to embarrassed by English ancestry).
But English ancestry was more common in the South in 1980 than anything else. The only counties in the US where majorities said they were only English that year were in Eastern Kentucky.
Just as people don't want to claim English ancestry because of negative stereotypes about "WASPs," so also many people would much sooner claim Englishness and be a WASP than be Scots-Irish and a "hillbilly."
Not really, the easiest way for various political parties to win votes was to whip up some anglophobia. It was one of the few things nativist and say the Irish could find common cause on (that and treating the Chinese, Indians and Blacks poorly)
You had actual shooting wars, skirmishes, boundary disputes, support of the Confederacy et al. Our foreign policy was also designed to contain British/read- English interests. It wasnt just Germans and Irish who wanted no business helping the British in WWI.
