That's cool but I'm not talking about Germany.

This is such a weird hill to die on

Interesting thanks for the information.

Regardless, people have been calling it Juneteenth for over a hundred years, it was made a national holiday as Juneteenth, I'm gonna keep calling it that.

The prisons. I mean more specifically the state or federal government ultimately but the prisons more practically.

The 13th amendment specifically carves out an exception to allow prisoners to be enslaved. They aren't just using political rhetoric: https://en.wikipedia.org/wiki/Penal_exception_clause

You know in movies and cartoons and stuff when you'd see like, a whole bunch of prisoners in striped pajamas, chained together breaking rocks or digging ditches or whatever? Those are depictions of an enslaved workforce.

Well they've got plenty of time to learn.

As far as I know most people consider Emancipation Day the day that the Emancipation Proclamation was signed into law in 1863, whereas Juneteenth marks the day 2.5 years later that the last known enslaved people were freed from the people who decided to just not tell them about the law.
