First, when anyone does this just say "no." If they're telling lies or something, that's an additional issue. I don't have time to go back and re-read y'all's conversation.
Some chrstian FReepers think that the USA is a special, holy, chosen country whose unique Fundamentalist Protestantism is the One True Religion Restored, that all our Founders were orthodox chrstians, and that our founding documents are divinely inspired (ironically, this latter belief is actually an official belief of mormonism). Now--I know this attitude is hard to put up with (it raises my blood pressure too, just like the "King James Only" people), but it is an unfortunate tendency of chrstianity (with belief in a . . . ugh . . . god become man) to want to radically localize that "gxd" into the home country. Almost every single chrstian country in history has at one time or another tried to make this claim of being "THE" special chosen holy country. Have you ever heard of the Armenians? And the Ethiopians not only claim that their imperial dynasty was descended from Solomon and Sheba, but to actually have the Ark of the Covenant as well! American chrstian nationalism is relatively recent and mild compared to the chrstian nationalism of older countries.
Now I am not Jewish but a Noachide, which means (since technically all non-Jews are Noachides) that I'm not a minority in exile. Not being a minority in exile, I don't play the "religious freedom" card very often, because I'm a fundie. (Most Orthodox Jews are fundies, but being a minority in exile don't feel comfortable in "coming out" about it.). This means that I don't justify my beliefs on any permission granted by Thomas Jefferson (whose anti-Biblical religious beliefs were certainly problematic). I'm a Noachide because that is what G-d commands. It doesn't matter if it's "un-American" or not. All that matters is what G-d says . . . not what the traditional beliefs of one's country may be. The notion that everyone is supposed to automatically be the religion of his country's tradition regardless of what it might be is patently ridiculous. Are all Arabs supposed to be moslems?
So . . . just my advice: if or when someone implies that Judaism is "un-American" simply because it isn't the religion of the majority of the people who settled this country in the seventeenth century, don't wave the First Amendment around as if Judaism were based on it. It is not. Judaism is based on the Torah, nothing else. And it requires the permission of no one, most especially a bunch of eighteenth century "enlightenment" deists, to practice.
So instead of sounding like the ACLU, just take a chaw of terbakky, spit, and say something like "Hot dammit, y'all! Ah don' keer WHO-ALL started this country, y'hear??? All that matters is what GAWWWWWWWD (and be sure to pronounce it like that) says, and He didn't found no johnny-come-lately liberal religion like chrstianity!" Then take another chaw, hitch up your bib overalls, and walk out like you owned the place. That's what I always do.

***That is good advice to your friend. She’s been pinged to 2 recent threads on judaism and can spread her wares over there in the religion forum where it belongs and she won’t be accused of hijacking the thread.
