These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
For context, prior to the 07 October revision, page 83 featured Charlie performing a sexual act on Jamie against his explicit consent, and Jamie dis-associating so as to make the experience pass more quickly. Although the arguments surrounding Charlie's actions against Jamie had many, MANY intricate and painful facets, the biggest and/or loudest camps were divided primarily between A: Those who felt that Tab's choice to make Charlie commit an act of sexual violence played dangerously into a larger trans-phobic cultural narrative, and B: those who either saw Charlie's actions as —if not forgivable— comprehensible given her extensive back story, or who focused on other things like the fact that it honestly portrayed a man as being susceptible to sexual abuse, in spite of a number of cultural assumptions to the contrary. There was a LOT more to it than just that, but better to be brief and LetOtherArticlesWithBetterWriters give you an idea of some of the complexities involved. The original massive and contentious comment thread has since been taken down, though Tab has said that he is keeping a copy for posterity.

Tom calling Jamie gay after he began dating Charlie in the eyes of many, including Charlie herself, who cuts off all contact.
This is thrown hard into perspective, however, when Charlie forces herself on Jamie. However, following the revision, it's also deconstructed. Charlie feels incredible guilt for her actions and is quite clearly shocked at what she was within inches of becoming.
