I think (wish to believe?) Sablin was a Leninist, who wanted back ideals of the 1917 Revolution, but some leftcoms may be lured to him by opposing USSR when it did not follow their expectations.
The warship is called Dzerzhinskiy, has she some references to Sablin?
I don't know Sablin exact political stance but even if he said he was leninist and was absolutely correct, what he did was not much corresponding to this, since it was adventurism. Even comparisons to the battleship Potemkin are very loose at best, and at worst it's something between blanquism and SR's. Again i might be mistaken since i don't know about him, but this is seriously first time i seen any ML praising Sablin, 100% of other cases were ultras. A lot of HoI4 players since Sablin is featured in TNO mod, but again as everything in TNO is more of carricature than real character.

Not really except the same class, but i read about the class and it is still in service without name change, which is helluva rare in case of Russian ships inherited from USSR, especially name like THAT.
