Fascism, at least at the time, would be militaristic, nationalistic, propagandist, corporatist, personality-cultist, and totalitarian.
-militaristic - idealizing the military structure and discipline and applying it to personal life and political discourse, equating dissent as treason.
-nationalistic - believe that the nation and the national government is supreme over particular regions/towns, and that people must sacrifice for the nation's good, whatever the leader says that is
-propogandist - check out Nazi and Soviet propoganda, and the indoctrination into those societies. They used a willing and compliant media to spread their messages to the masses
-corporatist - corporations and governments must work hand-in-hand, sometimes to the extent that corporations become enforcement arms of the government regulations or even writing government regulations of their industries. Governments may even own the business, or at the very least subsidize it or give it a monopoly in some fashion
-personality-cultist - There is near deification of the leader of the state and unswerving loyalty to that leader is called for, and any criticism, no matter what, is decried and denounced as disloyal or the like.
-totalitarian - the government has the right, duty, and/or obligation to regulate as much of your individual life and choices as possible, from the foods you eat, to the schools you go to, the car you can drive, the appliances you can buy, to the health care options you can choose.
I was reading a book about it that had some really good examples that I'll edit into this post later. But those six points cover most of it.
