There's a town in Ohio where the Fire Department blares a siren at 6:00 p.m. Black people don't like that. Young white people don't understand, because to them, it's just a siren?
But people that know white US history, know that there were hundreds of sundown towns that blared a similar siren at 6:00 p.m. This was intentional terrorism against Black people.
The siren meant that if you were Black and in the town after 6pm, you could be beaten or killed.
The Purge IRL, but only for Black folk.
