I literally said nothing about anger, you may be projecting. It's simple; we use history to inform us of the future. Realizing that part of the rise of fascism now is based on trying to return things to the 50s standard of where minorities, gay people, and women were subservient helps us to better fight against the rise of facism. We can use further back history like Germany, etc. to compare the patterns to, to better help us fight it. That's how it works.

Fascism wasn't being fought in the 50s because you has multiple basic slave classes to support those in power already. It had already won to a large degree. We now have to make sure it doesn't get back there.
