Well now you're 'gas lighting history' Harshaw. One year before Washington's farewell address, Washington helped to win support for the Naturalization of 1795, which included the Oath of Renunciation and Allegiance, which itself was inspired by the issue of people coming to America to live, while holding loyalties to their country of origin, or any other country to which they might hold an allegiance.
"I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state or sovereignty of whom or which I have heretofore been a subject or citizen."

The practice of dual citizenship would eventually pave the way for people to celebrate their divided loyalties, and Afroyim v Rusk was used to finally decimate the founding fathers vision of what citizenship in the USA meant. The case involved a man from Poland named Beys Afroyim, who moved to the USA where he became a citizen, and then proceded to vote in Israeli elections. His dual loyalty didn't even include his country of birth, but rather a county he wasn't born in, or living in.

The word 'antisemitism' was invented in the 1860's in Germany, and now carries more weight in the American collective conscience than the term dual loyalties. Who's been gas lighted Harshaw?
Try not being an apologist for disloyalty in your own country, and maybe you won't see antisemitism everywhere.
