At least online, it seems like the only Americans who call themselves far left agree those are all centrist positions. It's only "centrists/progressives*" (moderately far right Americans) and other flavors of far right who still often dont generally call themselves far right (trump enthusiasts, alex jones types, proud boy types) who label basic things like universal health care a far left idea or just call it impractical atm.

*I feel like 10 years ago, people who were at least moderately left were the main people using this term, but in the last few years, people right of center have been using the label to try limit progress by pretending they're just trying to be practical/realists about what can actually be done.
