You were the one who didn’t understand plain English. I posted something worded properly and you didn’t read it correctly. You are the one with an issue there, not me. If you have a learning disability or are dyslexic or something, that’s your problem. Not mine.
And in your semi-literate mind that’s the simplistic version of history you are capable of comprehending. However, as explained you already, the “first” isn’t the only parameter, nor is it a particularly significant one. It wasn’t an “athletic race”, it’s far a more complex issue than that. The abolition movement didn’t end when Britain or the United States abolished slavery and neither did their efforts to end slavery beyond their boarders.
By your simplistic understanding, after Britain abolished slavery, they apparently made no contribution to the abolition movement. Or at least none that you can bother to recognize. The same is true for the American abolitionists who you dismiss. It’s not a finish line, that once crossed it’s over. It’s not an issue encapsulated within one country’s history. It was a global issue. There were on going efforts by both countries, to abolish slavery beyond their boarders. That’s what sets Britain and the US apart from countries in “Latin America” which weren’t even self governed.
You can try to dumb it down like that, but the documented history is more complex than you and your “finish line” mentality will ever admit. The only one bringing “American exceptionalism” in to it is your triggered woke self. Acknowledging actual history and the significants of actual events and actual people is not engaging in some nationalistic rhetoric. You are the one who has to down-play the impact of figures like Frederick Douglass to maintain the delusion of your woke gender-studies world view.
