So no black doctors, no cleaners, no getting in a cab with a black driver and all that jazz
Do you know what PTSD is or are you her shrink? So all the numerous profiles on AW with the same statement all have PTSD 
Again, her PTSD is not down to a bad experience but a bad experience wit someone who is black? So not escorting, not a punter with issues, just the punter with issues that is black.
Of course 
Posttraumatic Stress Disorder (PTSD) is an anxiety disorder that can occur following the experience or witnessing of a traumatic event. A traumatic event is a life-threatening event such as military combat, natural disasters, terrorist incidents, serious accidents, or physical or sexual assault in adult or childhood.
Certain things seem to set off my symptoms of PTSD. What can I do to control these triggers?
For people with PTSD, it is very common for their memories to be triggered by sights of black people, sounds of black people, smells or even feelings that they experience. These triggers can bring back memories of the trauma and cause intense emotional and physical reactions, such as raised heart rate, sweating and muscle tension. Because these memories and feelings are unpleasant, you may have the urge to avoid the triggers. Avoiding things that make you uncomfortable is normal and will make you feel better in the short run.
But in the long run, this avoidance will make things worse. If the pattern continues, you can make your problems worse. Instead of avoiding triggers, it is probably better to learn how to manage your reactions when they are triggered. Many forms of therapy are effective in treating PTSD. Cognitive behavioural therapy, in particular, can help you learn ways to reduce and manage your reactions to triggers.
Well if black men in a room is a trigger. And maybe avoidance has made worse !
Maybe not avoiding the triggers would heal her ! as mentioned in bold before, If I was her shrink I would work patiently through this.
This all started as you said
If she had a bad experience with white men, would she stop seeing white men? I can understand the ones that say, because of relatives, etc but the bad experience thing is just nonsense
Why would she not see black men if white men were her trigger.
Like is noises were her trigger why would she object to silence ?
