I can't really understand the downvotes here, these are facts. Here's a brief history of anti-immigrant propaganda in the US through the years to back up OPs claims. The anti-German sentiment in the late 1700s is new to me, to be honest.

Franklin on Germans: “A Colony of Aliens, who will shortly be so numerous as to Germanize us instead of our Anglifying them and will never adopt our Language or Customs any more than they can acquire our Complexion.” [1] Boy was he right, Freunde.
