In a similar but different vein...
My Mom's last husband (wont call him step dad coz he wasnt - they got married when I'd already left home & was only a short marriage) was an abusive violent fucker (unbeknownst to me - as I said I'd left home by then & me Mom kept it all under wraps until the divorce.... I'dve taken a bottle to him otherwise)...
Anyways... a year after their divorce he started to called himself Jennifer, dress is womens clothing & has (we are led to believe) gone for the full op
Crazy mixed up abusive bastard....
PS My mom used to get her own back in her own ways.... like cleaning the toilet with his toothbrush....
