American media is calling this an act by Anarchists, they seem to have lost all sense of what words even mean. It is a fascist coup being attempted by a fascistic mob.
In light of this, here are a few things that you could read to better understand the fascists' ideology:

Ur-Fascism by Umberto Eco
A short essay by a man who grew up around the Italian blackshirts, as a child indoctrinated into fascism. Eco gives a "fascist minimum", breaking down the essentials of the ideology and how it differs from Left authoritarianism.

Fascism: What It Is and How To Fight It by Leon Trotsky
A Marxist approach to the fascism of the 20th century, seen through Trotsky's writings. While the title is self-explanatory, Trotsky also highlights key strategic failures of Left parties of the time.
