Kathy Baldock is an evangelical Christian who also happens to support LGBTQ rights. As she explains on her personal ministry’s website, that required a major shift in her thinking a while back, but she’s been trying to make amends for it ever since.
That gives you an idea of how much you can trust Amazon reviews. Obviously the author and homophobic supporters reported her posts and managed to get those "negative" reviews removed. The shocking thing is that she was banned from leaving further reviews.
I think more likely it is a self righteous employee who took it upon himself or herself to take down the reviews whi9ch went against his/her religious beliefs.
