Where is she going that she's being misgendered? I can't say I've ever gone to a restaurant, store, anywhere and had anyone address me as ma'am. I wonder how much of it she's just imagining. I'm starting to worry she's going to get violent too. She's been coming off increasingly unhinged.
I have lived in the South but currently do not, nor anywhere near, and I get ma'amed all day long. Both live and with just about every phone customer service rep, wherever located, except by the reps who use "Miss______," (either first or last, though usually first, which because I have Southern roots delights me, even when it's clearly someone from the Philippines or India).
But on PT, wow. I delved into this thread about a week ago for the first time, and the condensed arc of the last 8 years has been a lot.
PT needs to get away from her parents, period. WHY they haven't gotten her a Stephanie C.-style cheap apartment long before now shows that they are all fucked up and codependent/crazy. She may ultimately be incapable if taking care of herself, but she should have at least been required/enabled to try, given the friction in the home. At this point, and for a long time, though, they seem inept and incapable of taking action.
Second, they need to flea-bomb her room and treat it for bedbugs. She should also have a self-cleaning litterbox if it's going to be in her room.
I agree with those seeing major trauma in her life, resulting in control issues and very fucked-up ideas of herself, sexuality, vulnerability, etc. The cosplay, earlier insistence (for a good 15 years, assuming the thread is somewhat accurate) on being Japanese, and overt sexuality (now turned to rejection of same) all seem like a trauma cope. Add to that what is at least a genetic predisposition to bipolar or some kind of mental illness, and the influence of living with a parent with some kind of mental imbalance, and you get someone who is an annoying twit of a hothouse flower who is perpetually paranoid with misplaced anger, heightened (to the point of irrational) sensitivities, and on guard against any real or imagined transgression of her person/personhood. PT is a wounded animal ill-equipped to find peace in the world and unable to distinguish what is and what is not within her control, and hobbled by her unhealthy dependency on those (known and unknown) she inversely and deeply needs to break free from.
I'm not entirely convinced she's not developmentally compromised intellectually as well, but whatever might be intellectual issues seem far outweighed by emotional and psychological ones.
