Reading the reports you linked to Nitro shows me that this man has rationalisations for everything but I’m not sure his argument of ‘I couldn’t actually carry out my threats because I’m under lock and key for 22 hours a day’ is a very convincing sign that he’s not a threat.
The fact that any woman who does something he doesn’t like gets a disgusting rape threat (often very detailed) shows this man is a threat to women and enjoys using sexually violent imagery to terrify them.
Given that he has previously attacked women (and tried to pull off his social worker’s eyelids), and given that he shows no actual remorse just rationalisations and proffers excuses from his bad childhood (like the men from Gisèle Pelicot’s trial) I don’t think he’ll ever be safe to be around women.
He also seems to enjoy using his legal status as a self-declared woman to confound the legal/justice system by asking for special considerations during trials, and reporting from trials, and as another rationalisation for why he threatens to rape with an implement.
