Yep, my point being that a trans man (AFAB) and a cis man (AMAB) both have their bed nucleus of the stria terminalis roughly the same size, twice the size of a woman’s. A woman’s is half the size of a man’s, regardless of whether she’s trans (AMAB) or cis (AFAB). So regardless of what the gender is assigned at birth, the relative size of the bed nucleus predicts the gender that the individual feels most comfortable as.
Ah yes, the classic sign and countersign in memes cant.
