Fair point. but counterpoint - nobody alive today was around for the others, except for maybe the nazi sympathizing America first committee in the early 1940s. Anyone around today would’ve been children then. The modern idea behind it (albeit less overtly hate driven) was grand dragon dude
Plenty of people do. It’s obviously changed over time, but trumps America first is more in line with fields’ America first than the America first of the ‘40s. There are too many people that still hold onto that hateful rhetoric in some parts of the country. Hearing “America first” again would be like a dog whistle to them.
