Usually the phrase "I'm not trying to be political, but..." is followed with something immensely political. So, well done, you've found a way to politicise a game which is actually pretty apolitical in the scheme of things. To boot, you're getting very easily offended by the most marginal, subtle of references to Presidential candidates and voice actors, and that's just hilarious.
To start with, let's go over a handful of the villains in the game and break down how they are apparently right-wing:
Viktor Novikov - Head of a Spy Ring and owner of a fashion label. Sells information that leads to the deaths of many people across the world. Is an asshole and a bully to his staff. Hires assassins to kill FSB section chiefs investigating him. How is that a depiction of a right wing person? Unless "morally bankrupt scumbag" = right wing, in which case that's pretty damning.
Silvio Caruso - Genius bioengineer, made socially unstable due to years of abuse from his mother as a child. Don't see anything right wing there.
Sean Rose - Anarchist Terrorist, grew up a member of a radical Marxist cult.
Maya Parvati - Literally a member of a revolutionary socialist group.
The only target in the game who is overtly right wing is Marco Abbiati.
Wow... I thought it was lefties who were the easily offended special snowflakes. If that upsets you then I don't know what to say. The reason Donald Trump is a laughing stock is not because he's right wing, it's because he's a complete and utter joke. That reference was the least offensive thing in the world.
For starters, the voice actor for Dino Bosco is William Mapother - AKA the guy who replaced David Bateson initially in Absolution. It was a funny little reference, nothing more - And you see it as a personal slight against you or the fanbase. You're paranoid - IO are very kind to their fans.
...Is that really something to aspire towards? 2edgy4me racism? I can't believe you are offended by a reference in the game to David Bateson but you want to see people using racist slurs. Your priorities are bonkers. Are you also annoyed we evolved past thinking blackface was a good idea too?
