The Cizeron supporters on Twitter might be loud, but there are only a few of them. The vast majority of the responses have been hateful towards Cizeron and declaring him as evil, who will "not see the gates to heaven". I also see no reason to bring C/B into this discussion. This isn't about rooting for one's favorites.
For me, what saddens me the most is that once again, Gabi's autonomy is taken from her. Every time she attempts to tell her story, either the fans or the media twist her words or omit important context in order to make them fit narratives they already had (the fans) or to have them serve as better clickbait (the media).
This is Gabi's story, Cizeron is a character in that story, but she's the main character, and the way the book was promoted so far (either by fault of the media, her publisher, or both), has actually made it all about him when in reality she was trying to tell a much more complex an nuanced story, and was trying to dismantle the power dynamics in the sport. I really hope that, for her sake, this trajectory will change and the focus will shift back to her.
