The crimes I was accused of were of a non-violent nature: peacefully resisting the (illegal and violent) actions of the police officers, insulting (i.e. criticising) «political, administrative or judiciary bodies», organising a unauthorised demonstration. Most of the accusations have already fallen since the game was published, but a few are still pending, namely the insults against the impersonal «bodies» and the unauthorised demonstration.
I agree that in general freedom of expression should be protected, e.g. my freedom of expressing the idea that the police behaved in a very wrong way that night should be granted instead of trying to frame it as a crime. The same applies to my freedom of organising an Antifascist demonstration.
I disagree that all kinds of expression should be protected, for instance I would not allow any individual to bully weaker people with words and gestures. If a man sees a woman passing by and calls her a slut I would not consider that freedom of expression that ought to be defended. The same applies with using ethnic slurs against Jews, black people, gays etc.
Fascist slogans and rallies in paramilitary fashion are a form psychological violence against minorities, are harmful to the society as a whole and they are always used to prepare and organise actual violence against real people. For this reason freedom of expression simply doesn't apply to them, as it doesn't apply to ISIS apologists or promoters of rape.
