political theory that the far left and far right have similarities
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.
- [M]any people believe, as the "political horseshoe" theory states, that there is a lot more common ground between the far left, where Loewenstein dwells politically, and the far right views of someone like Betty Luks than people on the left would care to admit.

- [N]ormally it takes till middle age to realize that Left and Right are essentially at the extremes, the equivalent, totalitarian, they have different words for them. You know that nationalism, extreme nationalist, extreme socialism they don’t just meet in Berlin in 1933, they can meet at McGill in 1968, or whatever that was. So I became very acutely aware of the dangers, the hypocrisies, and sort of the extremism of the political extremes. And it cleansed me very early in my political evolution of any romanticism. I detested the extreme Left and extreme Right, and found myself somewhere in the middle.
- [T]he nutcase Left and the nutcase Right are alike in virtually every particular. They should get a room somewhere -- far from here.
