The thing is, though, sexual abuse is more than just "a failure in one area." What he did was not just a one-time slip-up. This was predatory and immoral behavior, and covering up of it, that persisted for decades until his death. He sued and silenced Lori Anne Thompson, one of the women he sexually abused, until his death in order to keep his abuses secret. He co-owned a massage parlor at which he asked employees for sexual services and sexually abused massage therapists. He engaged in extramarital affairs via text messages and emails and had over 200 photos of women on his phone.
Sexual abuse is not just a failure. Sexual acts in which consent is absent (which also include pedophilia, ephebophilia, inappropriate behavior with animals, most instances of incest) are forms of sexual assault/abuse. There are consensual sexual activities that would be considered sinful and harmful as well such as adultery, fornication, inappropriate contentography, etc. But what makes sexual assault/abuse much worse is the coupling of sexual immorality and the forcible violation of another person's body against their consent. An act that God intended to be an act of love becomes an act of hate, an act of power, an act of control.
Imagine you have a mother, sister, female cousin, aunt, grandma, niece, wife (if you're a man), daughter, granddaughter, female friend, etc. and she was abused by a well-known, reputable theologian/pastor and he never publicly apologized for it, covered it up, never admitted to it, and tried to silence her, you, and your and her loved ones when she, they, or you would try to speak up. Would you want him to still have a platform and the respect and adoration of most/all of the Christian world? I would not.
