It depends. "America First" doesn't seem like it took a lot of thought.
Yeah, that's a no brainer, right up there with Nation of Islam stuff and I think most people have the sensibility to see the extremism for what it is.
And of those people, there are those drawn to it like moths to a streetlight. You know, 'patriots.'
"In the beginning of a change the patriot is a scarce man, and brave, and hated and scorned. When his cause succeeds, the timid join him, for then it costs nothing to be a patriot. Man is the only Patriot."
Patriots is a fungible tag. You could even use the tag zealots, and that could cover just about any human emotional need.
