I'm a bit conflicted about this. On the one hand, like most people here, I got a huge amount out of reading her book, and I have nothing but admiration for her bravery in living openly as someone with a spanking fetish. I also think that she's done some pretty serious intellectual work in conceptualising the thing that unites us. Yes, "innate, lifelong and unchosen" captures it perfectly; and yes, like jsanon, I found her framing of spanking as fundamentally a sexual act and therefore not something to do to children both surprising and, even after much thought, compelling. After reading her life story in her book I found I was emotionally invested in her happiness - I was saddened to learn that the relationship at the centre of it, with a vanilla man, fell apart soon after it was published, causing her a lot of suffering. I have a lot of affection and admiration for her.
However, I struggle with the lesson that she's drawn from her own life experiences. She has a YouTube video where she basically tells the viewer that spanko-vanilla relationships can never work - the only routes to happiness are to find someone who shares your fetish or someone who's not fussed about monogamy.
As someone who's been having monogamous spanking fun with his vanilla wife for over two decades now, I know this is nonsense. But I didn't know it was nonsense early on in our relationship, and if I'd watched Jillian Keenan's video on the subject at the wrong time... I could easily have blown up something good and beautiful by pushing my then-girlfriend to accept that the only way for me to be sexually fulfilled was by playing with other fetishists. I suppose I worry that because of her own traumatic experience, she's now committed to the profoundly negative idea that being a spanko means you're incapable of having a monogamous romantic relationship with a non-spanko. I have visions of people breaking up with girlfriends/boyfriends they love because of this pessimistic message, or causing intense pain to their husbands/wives by presenting them with a choice between 'consensual non-monogamy' and divorce.
It's a relatively small thing compared to the good she's worked in the world, I admit, but ever since seeing that video I've not been able to look at her and think she's an uncomplicated blessing to people like us.
