You seem to bring some wild things to a single simple idea of bias in grades. Making this discussion about mistreatment and abuse is as appropriate as insisting on talking about sexual assault at the workplace in a discussion about gender salary discrepancy. Like sure, maybe you were traumatized by school experience, some of us were too, it's just not what the question is about. You can be traumatized by school with perfectly even grades as easily as you can have the most fulfilling experience even if teacher marked you up or down slightly when grading (eg like in the paper encouraging you with lower or higher grades according to what motivates you), these are just orthogonal.
