I would wholeheartedly agree with you if that was little-known, but — and I admit, I'm guessing here — I'd be very surprised if most people on Lemmy don't know he was a slaveowner and a rapist. This place is basically a commune of nerds with strong left-wing political opinions. I really don't think we need to preface things that everyone here already knows are bad. We're also talking about slavery, but don't feel the need to point out that actually, slavery is really not great (something that might be important to remind others of on, say, Twitter).
