What does that mean, how is a brain an opposite sex? A male can have female gene in the brain cells? That would be a mental disorder.
BWAHAHAHAHAHAHAHAHHAHAAA! YOUR feeble attempt to support YOUR utterly bogus allegation is to use a DEFORMITY? Furthermore YOU do NOT even understand the meaning of the term DISORDER. Clearly YOU do NOT understand the relevant TERMINOLOGY at all. Sad!
Thank you for CONFIRMING that YOU do NOT understand the term DISORDER as it applies to the BRAIN. ACCORDING to YOU being born LEFTHANDED would meet YOUR asinine "definition" of the term because the brain. PRICELESS.
