That's not true at all, actually - just a weird reddit meme. The European spectrum is fairly similar to the American one on social issues like abortion, gay rights, and marijuana. It's a bit more left on economic issues like universal healthcare are a bit more right on civil liberties issues like free speech, individual freedom and gun ownership.

> From US point of view even right wing European parties are socialists, that is how extreme late stage capitalism is.

Americans consider Germany's AfD or France's Rassemblement National as left? I don't know that that stands up to scrutiny.
