When you say "Someone finally writing about feminism with nuance and coherence." you are talking about feminism. The word "about" is the giveaway here - you're talking about feminism.
But let's clear up some of the fairly wild leaps in assumption you've just made -
Saying "Don't default to the position that women might be lying when they make rape allegations" isn't at all the same thing as "accusation is guilt". That is of course, a dangerous precedent. Fortunately it rarely happens. What does happen is that, as we see over and over and before it ever gets to court, women aren't believed or they're not the "perfect rape victim" (according to rape mythology standards) so it probably won't go anywhere. That, is the dangerous precedent we are living with now, so let's deal with that one before we worry about a hypothetical future danger.
I am not arguing for accusation alone to be enough, and I never have. Again, giving the women air time is not condemning the accused and never should be. I learned that in my law degree and have never disagreed with it.
It is about victim-blaming, because when you advocate for suspecting the accuser instead of the accused, (which doesn't happen in other crimes - unless you're non-white), you immediately unlevel the playing field. There is no balance. Balance would be not "building on" that assumption, to go back to the last para in the article. While there should always be a presumption of innocence when going into a case, the flip side of that should never be that the accuser might be lying. The one doesn't lead to the other.
Trust me, society in not swinging anywhere close to "we must believe in all victims" where rape and sexual assault are concerned. There is not one study to show that and many, many studies to show that women often don't report rape, when they do they're not taken seriously, they're put on the stand if and when they ever get to court, - but most cases don't get there and in many cases it's not because they're not credible, it's because of rape kits lying around un-tested, lack of post-rape testing etc etc. The lists go on.
Finally - "the recognition that false allegations exist — not that they’re common, but that they exist — and can be quite dangerous is a step forward. Let’s build on that." Reminding people that false allegations exist, is advocating for that mindset, which is not balanced or fair and sets the tables firmly against the accuser.
