Well the issue many people have is that the spectrum is drawn so that center is non existent, and everything left of it supports government owned means of production in some way, and to the right is private owned means of production.

To say anything is left of center, and also pro private company ownership of the means of production is just incorrect/ couldn’t exist.

So those people probably believe it you replaced the terms left/right with other terms, like leans blue or leans red, it would be more accurate. As blue in the U.S. is right of center. (Imagine CNN being against privately owned companies, we’ve never seen it)
