Think RB is referring to the horseshoe effect is and us probaly right .

The horseshoe theory, also known as the horseshoe effect, in political science claims that the far-left and far-right are more similar to each other in essentials than either is to the political center.[note 1]

It was formulated by the French post-postmodernist philosopher Jean-Pierre Faye in 1996,[2] but similar ideas existed previously.[3] Faye believed that the extremes of the political spectrum both represented totalitarianism of different kinds; this meant that the political spectrum should not be described as a linear bar with the two ends representing the far-left and right being ideologically the furthest apart from each other, but as a horseshoe in which the two ends are closer to each other than to the center.
