Here’s what the family has to say on the subject. There’s also the matter of the recently uncovered connecting room that allowed Thomas easy but secret access. I tend to think that owning and raping slaves is more than a flaw but that’s me. If you wish to debate whether his relationship with his 14-year-old slave was rape or not; did she have the right to say no?
