The number of false rape accusations is absolutely dwarfed by the number of rapists who get off scot free. While false accusations do happen, to set the standard at only believing women when the perpetrator is convicted in a court of law (which you can find people doing all over lib instances right now) excuses more than 96% of all rapes. There is literally a 4% difference between that, and just straight up excusing rape altogether.
In the particular case of Platner, there was already an accuser who didn't tank his campaign, because people were justifiably skeptical of her political affiliations. The second accuser, however, presented credible evidence, including records of conversations from long before Platner had entered politics. It was only at this point that many different progressive figures who had endorsed him withdrew their support and called on him to drop out. So any attempts to shift the goalposts and pretend that people turning on him will just automatically believe anything and everything any woman says with zero skepticism, are obviously complete bullshit.
"Why did she keep quiet until now?" The vast majority of rape victims never take the case to the courts, ever, because they know that the chances of anything actually coming from it are incredibly low. And when the perpetrator goes free, they will now be in the position of looking like a false accuser, with the social stigma that comes with it.
Here's a little challenge, a way to conceptualize this. Roll a D20. On anything but a 1, a rapist just went free. If you do get a 1, roll it again. On a 17 or higher, the rapist still goes free. Keep rolling that die until you convict a single rapist, and post a comment telling me how many rapists got off before that.
Also, just a reminder: Platner is already out. The justification of, "We need to defend him because he's the only shot against a worse evil" no longer applies. At this point, anyone defending him is just in it for the love of the game. Frankly, if you were excusing his red flags before, you should be reconsidering whether your way of thinking was flawed. But if you're still defending him even now, I don't even know what to say. If no part of "rapist killer-for-hire with a Nazi tattoo" is a deal-breaker for you, then you are not a progressive by any stretch of the imagination.
Now, I try not to talk shit without having the receipts. So here's a little selection of what I'm talking about:

Ukraine is a difficult example, and I think we can safely say that the Soviet approach didn't work, and that's a key example that we can look at when evaluating the theory.
Like you said, Lenin's approach in practice wasn't consistent with his theoretical arguments. The approach was supposed to be a compromise between those concerns, as well as strategic concerns (the risk of divide and conquer) and political concerns (different factions calling for different things). But whatever his intents or justifications, the fact that Ukraine is such a mess today says that something went wrong in a big way.
It's easy to say that Ukraine should have just been given full independence, and that's probably correct, but we also don't know for sure what would've happened. What implications would that have had for WWII? Perhaps the strategic difficulties would have been offset by presenting a better image to other countries and getting more support.
Applying the theory to the present conflict gets even messier. In theory, Ukraine being independent would be a good thing, but in the current conflict it's really more about which sphere of influence it's in. The question of what to do when there's a secesionist movement within a nation that's not fully developed is particularly thorny. I really can't see any way things could work out for that region, unfortunately, so my stance is just to leave it alone.
In general, it's an enormously difficult and complex question, especially in practice, and the best we can do is to try to establish basic guidelines in the abstract, while looking at each situation case-by-case.
