The difference is that in fascist politics, the justifications are lies.
The US didn't invade Iraq to "liberate its people", and federal thugs aren't abducting people from the streets to "protect federal property".
Those are lies and transparent pretexts.
In non-fascist politics, the justifications aren't dishonest pretexts. For example, when non-fascist Roosevelt established Social Security, the stated reason was to safeguard "against the hazards and vicissitudes of life".
That was not a lie or a pretext. It was true, and that's the difference.
