A similar observation is the "horseshoe theory": "The horseshoe theory in political science asserts that rather than the far left and the far right being at opposite and opposing ends of a linear political continuum, they in fact closely resemble one another, much like the ends of a horseshoe."[1]
The problem comes with narrowing all political variation down to "left" vs "right". More dimensions are needed to tease apart the differences / similarities.
