I kinda get the anticommunism propaganda point, there already were anticommunist talking points back then, though I do feel like society as a whole has become much more brainwashed by the huge volume of anticommunist propaganda that exists today compared to then, it's not far fetched to say that today there's a whole industry of automated anticommunist and fascist propaganda with smart algorithms picking out the most vulnerable parts of the working class that are going to suck it up.

The single party thing is not true, even from this text you can see that there are already fractions, the biggest one being the Bolsheviks and the Mensheviks, but there are also mentions of people leaving the party because of disagreement and breaking off into their own groups. And also there's the factions before the Marxists started gaining ground that are subtly referenced here too, like the adventurists that believed in assassination strategies and another party believing that the revolution can only happen by the peasants, the Marxists had to argue with both until it became clear that their ideology is the most materially and scientifically grounded.

Starting fresh also comes with negatives, they had no idea what was coming for them and only had some very limited examples to draw from like the French Commune. We on the other hand have a whole century of revolutions, successes and failures to analyze and perfect when revolutionary conditions arise again. It's not all bad for us, and the decades of propaganda are weak against the wrecking ball of material conditions radicalizing the working class once again. You can already start seeing this with young people, the truth always wins eventually, as long as we survive long enough for it to happen.
