therapists are often quite bad at understanding the effects of prejudice. like framing prejudicial dislike as a symptom of social anxiety. and so on.

however, the one thing is that it might be really hard to find a Black therapist in son's area, especially a Black man. I 100% think it's worth looking, esp with telehealth, but also important to be prepared for a long search (which is why his family need to be supportive & help out if able/son is comfortable with them helping).
