With all due respect, I highly doubt, that the word 'fascist' is known throughout New Eden. This word is based on Roman symbolism, that is unknown in game universe.
Moreover, it can't hold negative meaning in New Eden, since it got this negative meaning only after Italy has lost the war.
Instead of word 'fascism' for RP I think 'national corporatism' would be more adequate.
The word "Quisling" Is not known in New Eden either, but it's still in use IC as an auto-translator word for 'Traitor' just like "Judas" would mean the same thing.
Remember always that specific characters speak Amarrian, Caldanese, Gallente, Brutor/Sebeistor, Intaki and so on, but every Capsuleer's available technology translates that to whatever they want.
No-one in EVE speak English.

As for the subject, I find Seri's aggressive use of 'death to the fascists' in describing the FIO-SDII as somewhat offensive - it adds a trait to a faction In-Game that is not absolutely accurate, especially not regarding the actor's rather level-headed way of dealing with the situation. Freedom of information and speech and so on is tempered by security needs. (The eternal dilemma for Democracies.) Everyone did not need to know what the FIO was doing, and the FIO did not need to be treated like shit for it.
They were, IC. That's cool, that's RP. We don't need to continue that into OOC - it goes to places like 'all Amarrians are slaving assholes IRL' and such pitfalls.
