If you see left and/vs/or right ideology like this,
<-----[Extreme Left]-----[Left]-----[Center]-----[Right]-----[Extreme Right]----->
and can bend it into a loop to see it like this,
[Center]
---
[Left] /// \\\ [Right]
--- ---
\\\ ///
---
[Extreme Left/Right]
then you might be able to consider how we've been purposefully misled to not see this,
[Good]
---
///|||\\\
[C e n t e r]
\\\|||///
---
[Evil]
and It might also explain why there's so much confusion between left and right where only two aims are clear: the many extremes walking the wide path, and the few centered walking the narrow path.

Fascism is pretty centrist, really. It's not exactly fair to consider the worst abuses by wartime fascist nations to be "what fascism is," especially considering that our constitutional republic did many of the same things during the same wars.
