I am of the opinion that 'sensitivity readers' and the equivalent do more harm than good. Not only does it lead to a lot of interesting grit and nuance being eroded from various aspects of a make believe setting but it dampens immersion as well. Worse yet, many writers are trained to self censor and hold back on what might otherwise be a bolder story beat.
What appeals to an individual in a particular setting often differs. We all have our own personal tastes, after all - especially when it comes to characters and themes. Some people root solely for the protagonists, others prefer anti-heroes, antagonists or outright villains.
Purity spirals, then, are not uncommon amongst those seeking to alter various established settings. Which in turn leads to some rather alarming and mean spirited cult-like behaviour. Any preference counter to their own is to be sabotaged - you see this quite often with the deliberate elimination of certain elements of established settings.
There is also a habit of ignoring and shunning minorities who speak up and state that they do not want to be present or reflected absolutely everywhere. I despise tokenism and negative stereotypes, so as a gay guy I can safely state that most attempts to cater to me fall flat. It's one thing to have a character who just happens to be gay, though it is often very obvious when that character is designed to fulfill a quota. It's often dressed up in hollow corporate activism, too, which again...a lot of us do not care for.
