You are probably right, because research shows time and time again that brain atrophy, especially the amygdala, is caused by extreme neglect at a very young age, not from peers in later years. I can't remember the study off the top of my head, but it involved bringing children into a room with a stranger, and seeing how they reacted when their guardian left the room. Abused or neglected children either didnt react at all, or were constantly sporadic whether their guardian was in the room or not, indicating a malfunction of their fear complex. Brain atrophy is pretty rare outside of congenital or genetic defects while in gestation as well, since our minds are constantly reforming connections that we injure from accidents and or traumatic events, so we never really "lose" gray matter the way they are trying to claim. If it was really caused by "racism", the amygdala would light up like a Christmas tree from fear, not atrophy like in the case of neglect or abuse, which would indicate that they have something bigger to fear than a meager racial insult.
