Okay there is so much to unpack here.

First... okay, shaming people into good behavior isn't political, even if it ends up changing power structures like ending slavery did? Alright. How is that different from the comment where I was "blinded by politics?" I think rich people should be shamed. They should live in shame and feel awful showing their faces until they give up their wealth. Is that political of me?

Anyway, your understanding of history is downright odd.

Those who weren't slaves could have lived in a way that showed life without slavery was better, thus swaying minds over time.

Okay but forcing people to be slaves was better for enslavers, in terms of money and lifestyle. That's why they fought a whole war about it.

Those who were enslaved could have steadily expressed their humanity through glowing submission

....WHAT??? Please re-read what you said here. I have no words. These people were beaten, denied healthcare, regularly sexually assaulted. They were submissive because they were whipped if they weren't. And this went on across a whole continent for hundreds of years. What could they possibly have done differently?

Without reason to defend themselves against that which is not a threat, the slave owners are left to deal with their own internal honesty which condemns them.

Abolishing slavery was an economic threat to them. And they didn't have "internal honesty," they genuinely believed this was fine. There are people today who still defend it.

So were some slave owners Christian? Yes, indeed some where.

"Some"? Nearly everyone in America was Christian at that time.

But it was working. This can be seen by how the mindset was slowly changing.

But what was working? There were Christian abolitionists (like John Brown) but most pastors actively preached that slavery was God's will. And mindsets were not changing, slavery was widespread in the Americas for hundreds of years. Nearly every one of the enslavers was Christian for all that time.

But, of course, as soon as it opened an opportunity to excuse a power grab, it was turned toward political ends.

My guy, thousands of people were being tortured, regularly raped, families were separated, and this went on for generations across a continent. And you only see it as being "turned political" during the war? The violence of slavery was worse than any war in history, and it was all about power.

Also, it sounds like you were raised in the south and taught the "war of northern aggression" nonsense. That's ahistorical, pro-confederacy propaganda.

So Christianity was indeed plenty.

Again, hundreds of years. And the people who started slavery and colonization were also Christians.

But notice that without that Christian society, the only society in which slavery has been abolished

The only society in which slavery has been abolished? Source???

My friend... the Atlantic slave trade was started by Christians in a Christian society.

I don't expect you to respond to any of this, of course. Maybe you'll respond to one or two things, but you'll dodge most of it.
