Is that controversial statement a common one in that ideology? An official one? Do many groups from that ideology subscribe to it?
You keep using the phrase "feminism", a memeplex that's as massive and diverse as any social movement, political ideology, or religion. But it's easy to oversimplify and be reductive towards such a memeplex, which includes members as diverse as Susan B. Anthony and Gloria Steinem, Zoe Quinn and Ariel Levy, Andrew Dworkin and Malala Yousafzai. You have to understand when dealing with a hugely variegated ideology it's unhelpful to speak in absolutes.
The "memeplex" offers no such nuance to any of those that they oppose; and for all the claimed diversity within the movement the resultant behaviour remains the same.
On the contrary, memeplex indicates quantity, size. A massive ideology with a thousand schools of thought inside. J.K. Rowling and Charlotte Clymer both identify as feminists. So do both Naomi Wu and Sarah Jeong. Such an umbrella term of ideologies contains myriads of sub-ideologies, many of them often in direct competition and contradiction with each other. To judge such an umbrella based on a single facet is to equate all of Islam to Salafi jihadism, or all of Christianity to Joel Osteen. It would seem that I am not the one operating without nuance, in this discussion.
> behaviour illustrated in just one example I have given.
A single statement from a single video? Perhaps that's the measure by how you judge all ideologies, but most do not subscribe to that heuristic.
> I stated the situation and gave an example when pressed for evidence.
And thus it is up to you to further prove that such evidence is indicative of the ideology, broadly.
The groups public behaviour indicates the ideology just fine; and when a group becomes publicly malicious enough on a large enough scale the onus is on the defence (eg its a given the nazis were evil; someone defending them doesn't get to come in and just hysterically scream "show me the evidence" because its public knowledge).
We have seen it over and over again in universities, in the corporate world. We have seen it in their numerous attempts to stifle free speech and to abolish right to fair trial. We have seen it in their uniform hypocrisy (were gendered insults still considered bad or is that mansplaining?) We have seen it in the trope of sex predators using the identity as a social shield for themselves.
You are being a denier at this stage.
As for answer 2, I've shown what basic searches can come up with. "why im not a feminst" might give you what you're looking for.
Answer 2: So I did the Google search as you requested, and read about the book [1]. I hadn't heard of it but it looks interesting, thanks for recommending. From what I can tell, it's central claim is that feminism has an image problem due to it being co-opted by the US right-wing which she calls "choice feminism", and the remedy is a need to return to a leftist concept of what she calls "radical feminism". Is that what you're saying?

The search for me at least brings a number of articles which highlight common criticisms of the movement such as rampant sexism, advocacy for abolition of basic rights (free speech, right to fair trial etc), general hypocrisy and bad faith action (see the Cathy Newman vs Jordan Peterson interview for a great example of this)
Perhaps when you search with your normal Google account it's skewing to different results. This particular book and the articles discussing it are critiquing modern feminist movements as too conservative, from what you perhaps would call a "radical left" perspective. I find it interesting that this is the exact opposite of "the general criticism at the moment seems to centre on the radical lefts takeover"!
I personally feel my incognito Google search captures the current zeitgeist better than your search, that people are fed up with conservatives and want a "radical, fearless call for revolution" as Google's auto-summary of my search put it. That said, ultimately it's all "bubbles" all the way down, as there's no such thing as a so-called "algorithm" (ranking formula, etc) free from ideology, so ¯\_(ツ)_/¯
All the other summaries on Amazon are similar, i.e. the very top description (New Yorker): "The point of 'Why I Am Not a Feminist' isn’t really that Crispin is not a feminist; it’s that she has no interest in being a part of a club that has opened its doors and lost sight of its politics—a club that would, if she weren’t so busy disavowing it, invite Kellyanne Conway in"
Having never read the book or even heard of the author until you introduced it to me I don't care one way or the other, but it's clear from a reading of these descriptions that her book is a critique from the left.
And plenty more for the willing student; however an ideology that considers "men are on average taller and stronger than women" to be a controversial statement might understandably place some difficulty on those in need of finding these things.
And funnily enough the definition of a group has nothing to do with how it behaves; or are you suddenly going to proudly identify as a mens rights activist? I suppose its just as well that naming North Korea a democratic peoples republic magically fixed the place overnight as well.
