She is quite centric too and has stated that the success of the women's movement is because of her, and her only. (I'll have to find that link.)
Yes, I've heard her say that on videos. It's rubbish, & it's a pity because it makes it easier for some feminists to dismiss her.
I've also heard her speak (back in 2018 before she was famous and before she was a bleached blonde!, and just recently at a radfem conference) - she's charismatic & compelling, and very charming. She came across as quite kind as a person.
Still, the women's movement has always had these charismatic larger than life characters - eg. Germaine Greer.
I think Kathleen Stock really hit the nail on the head at an online meeting she spoke at - women are not very goods at disagreeing with other women, or being disagreed with. It's a part of our socialisation which keeps us back, frankly.
And we can see it on this thread, and other debates about The Letter. However, we need to remember that there's room for multiple points of view.
