I know - as an abuse survior I was highly motivated to take note of this when it became public knowledge. I can only speak for myself, of course, but my searching revealed nothing that would lead me to frame this man as an abuser or change my view of him. I see no evidence in any information about the accusation, nor in his behavior as a highly public person - while his sister's story is tragic, I simply don't believe the accusation.
Also, fuck you for this quote toot, asshole.
