an anonymous slave boldly demanded that the Chief Executive lend his voice to the cause of abolition. It is not known whether the author was a former or current slave; nor do we know the author’s gender.
Fake news from 1808. Most likely a political opponent attempt to bait him. Jefferson was completely happy with slavery; it was his main business, breeding and selling them.
It's hilarious how modern people read old letters from these politicians and think they really ran around discussion philosophy and actually believed the stuff they wrote about it.
Hate to break this to you all but these guys burned most of the letters than mattered and had what they REALLY thought about anything written in them, and most of those letters that survive were those intended to be read publicly; letters to close friends tend to be a lot less grandiose and more personal. They wrote letters to friends and foes alike, to newspapers, to churches, to labor uinons, to governors, etc., etc., etc. Took Jefferson over a week to burn his.
