I agree, a lot of the characters do have bigoted views however they are at least civil to an extent. My only point was that while the other characters such as F&E may be rude, they are never threatening to anyone else and at worst attempt to stir up problems which gets shut down quickly. Ashley is the only one of the cast who actively goes out of her way to consistently threaten and assault which seems out of place from the other cast.
I understand that Ashley may be your personal favourite character as the writer and I dont wish to berate the writing as a whole as it is genuinely excellent for the rest of the cast, however it would at least be nice to have an option to call her out when she is out of order instead of being forced to go along with it.
Maybe it would be worth slowing the escalation the more friendship you have with Ashley as currently if you dont do her story but do everyone elses, everyone else is facing their demons and overcoming trauma, meanwhile Ashley is running around like a mad-woman brandishing knives and attacking people and that's at friendship level 13, which is normally the point where you understand someones backstory enough to get an idea of who they are and how to fix their issue. You also dont fix someone with those kinds of issues by going along with their defence mechanism. Heck if you could call Ashley out and it lowered her affection then that would make sense. It could also introduce a mechanic where sometimes you need to be cruel to be kind like you do with Lin and her story of becoming free. As a mechanic, it could be a puzzle of sorts and would give you as the writer more opportunities to add even more depth and approaches to each girl.
I genuinely dont mean what I am saying here as an insult as there is a lot here to love and I want to see it improve even more than it already is, however I fear that anyone who has had to deal with the aftermath of an Ashley in real life will not take kindly to her actions and may be taken out of the game's world as a whole due to there being no choice to say she is in the wrong.
