It's notable that all of those are pre-democratic.
GP stated this.
Parent replied with a list of scenarios where violence created progress, albeit none of which featured universal democracy before the violence.
IOW, they are loudly agreeing with each other.
Yes, in 2025.
Sadly the United States abolishing slavery for ~4 million within its own borders in the 1860s did not represent humanity as a whole.
On paper the problem is solved because it’s illegal to openly buy and sell another person. In practice the exact same treatment and de facto ownership and exploitation of other people remain without any meaningful enforcement in many parts of the world.
They are very different levels of democratic access.
I blame how slavery is taught for the confusion. Slavery itself is a legal state where one's autonomy is fully controlled by another. Forced labor is something people commonly use slaves for, but the absence of labor didn't make one free - a slave allowed to retire was still enslaved as was a newborn born into slavery even before they're first made to work.
The use of social media to spread misinformation with a specific agenda also makes democracy impossible.
There has to be a line, however fuzzy, somewhere. Remember Trump used misinformation to steer a crowd who then stormed the Capitol. Incitement should never be covered by free speech protection.
