>like The “HECKIN wholesome Sablin v Yagoda”
Actually the devs have specifically designed the Sablin-Yagoda story to show how Sablin is both undermining Yagoda's efforts of stability in the Far East and also that Irkutsk can reform even if they defeat Sablin. The whole Sablin v Yagoda thing is not a black-and-white as you make it out to be, that's why Sablin-simps are often mocked (at least on the sub plebbit anyway) for being an idealistic wrecker.
> he does shit that Lenin...Just didn’t fucking do
For one, Sablin can be a lot more authoritarian if you go down the bukharinist path, or an idealistic libsoc puppy who wouldn't harm a fly. How Sablin is represented is down to the player to decide, not only the devs. It's called 'good storytelling'.
>SocDem-Populist party in the US being “German agents”
I may be wrong, but I believe this is a reference to the American anti-war movement which was full of both far-leftists and, obviously, nazi-lovers that ended up being infiltrated. I have not played the US yet so I dunno.
