It sounds like you might be talking about fellow Americans.
I enjoy talking with old style never Trumper republicans.
I have a lot in common with them.
However, I don't think I have anything to say to full blown maga cult members or me to them.
You've given me an idea though with your Alabama reference.
Yes many people would get that code for likely maga.
I suppose I could say I'm "from" San Francisco which isn't technically true but that code would work for many people including foreigners. But San Francisco is loaded in too many ways so maybe California would be better as a more generic code for not maga.
I kind of really like that idea -- CALIFORNIA.
For any informed person on the U.S. divide saying that would at the very least indicate a person who can't be assumed to be maga, and more likely than that, probably not maga. Then if they want to pursue a discussion, it gives them an in. Otherwise. probably enough.
