You know this is crazy. If Chastity thought she was Napoleon, would her mother and the nuts of the world defend her? No. She’d get treatment. So her head tells her she’s a “man” and she’s NOT sick? Being mentally ill depends on the lie your head is telling you. Some lies are apparently acceptable to SOME people.
