Never left the US? That's impossible, as they cannot leave something that they've never been to. A significantly large number of them appear to not be from the USA.
This is indicated by things like slip ups such as the accidental use of Britishisms,
mistakes about basics like taxes (one said we have a federal sales tax, another said that Social Security comes straight out of our regular taxes, another thought that the Salvation Army was a military wing of the Catholic Church),
keeping Euro hours, not knowing if it's night or day here,
having no idea what's the name of the their state,
not aware of what life in the US is actually like (when all those illegals were being bused to NYC, one of them said that he was glad that finally New Yorkers learn what it's like to have immigrants move in. New York. NYC IS Immigrant City, 1/3 foreign born, 1/3 the children of foreigners, 1/3 2nd or more generation American born),
posting homespun anecdotes of foreign places but not of America (one posted quite a few about Australia, until I repeatedly pointed out the pattern. He's the same fella that didn't know melting pot New York City has been the gateway to immigrants to America since it was New Amsterdam. Something like 70% of all US citizens can trace their roots passing through here, if I got that right),
and overdosing with the overtly overt peppering of everything with "our" and "we" and "us" (Americans).
The Toronto Trucker Convoy Protest was particularly hilarious, as tons of these United Statians who don't know the name of the state they supposedly live in knew who Kendrick Pemberton MP of New Brunswick was, or went on about some new Alberta beer law. Mind you, 2/3 of Americans polled literally cannot find Canada on a map. Not even I knew who Justin Trudeau was till I got active here.
There's actually a surprising number of Muslims here. Many won't come out and say it, for understandable reasons, but come October 7th, 2023, quite a few conflicted with their MAGA comrades. They were shocked as their comments sympathetic to prosecuted Palestinians were downvoted into lowrated oblivion, and they were attacked mercilessly by their former pals. At least one hardcore Trumper quit the site because of this.
Also on October 7th quite a few appeared to be Jewish but had never revealed it. Curious, as since I joined here in 2016, I'm one of ONLY 3 members I'm aware of to admit having Jewish blood, and I'm not 100% sure if my great grandfather was.
