TBH, I'm basically agnostic about it. As I've written I don't think there is any chance of even another amendment passing in the next 15 years or so. None of the latest proposals I've seen have any real traction.
I spent my formative years in Virginia, so Jefferson is close to my political and philosophical thoughts a lot. I believe he was a good philosopher, showed a varied interest in new and marvel ideas especially considering his inventions and attempts to bring new agricultural products to Virginia.
His religious freedom statute was probably his greatest document, and is ignored by many so called christians today. (I call myself a back pew Presbyterian). My wife was one of the first coed undergraduates at UVa and we've spent a bit of time there.
I don't believe he or any other politician of the 17th century should be judged solely on 20 or 21st century believes. He was a man of the times, not a deity. He inherited Sally Hemings from his late wife (they were half sisters, and basically a surrogate to her daughters after she died). Who knows what arrangements Jefferson and Hemings made other that his agreeing to free their offspring. The fact that Virginia law did not recognize freed slaves may have played into the picture since he did free on of Hemings brothers while living at Monticello. (The man bought his freedom)
