The far left loves to categorize everything at its right as "fascist". The infamous Berlin wall was the "antifascist protection wall". In Yugoslavia, you'd hear every day at the radio a rant about the "fascists", even though the country was communist.
There are many definitions of what "fascism" is. The best I think is to refer to the historical italian fascist government, to understand it.
Btw presidential immunity is not fascist, many countries have similar laws.
