It is not thinking the worst about a founding father!!!! People left to propinquity, with or without vow of marriage and fidelity elsewhere, HAVE SEX. it’s dishonest to not know this happens. And since in his case there was no marriage, I don’t even see a sin, other than the moral yet unlisted sin of owning other people, which we are forced to accept as a part of history.
I think no less of him unless he raped her every time, which I doubt. There must have been mutual feelings. They were a couple. I don’t have problems with it.
You’re engaging in speculation. Knock yourself out.
