Most other democratic countries would consider American liberals right wing, so

This really really depends on your definition of “liberals”. Communists always do this extremely dishonest thing where they lump a huge swath of the political spectrum as “liberal”, accusing “liberals” of hypocrisy yet being completely incoherent in what they are accusing

you know this dude who says “I’m a liberal… … … a CLASSICAL liberal that is”?

American politics is to the right of most of Europe, because Democrats didn’t move to the left as much as Republicans moved to the right. But in no universe are Paul Ryan and Elizabeth Warren on the same page, and Warren isn’t “right wing”.
