It seems like you're concerned that we're impartially holding British accountable but not others, while ignoring all the good things that the British did? I think a party can do good and bad things, and while there might not be anyone appreciating good things, it doesn't make the bad things they did any less bad.

There is a very popular conception of slavery that is extremely ignorant of history and present reality which essentially implies slavery is something that white people invented to oppress darker skinned people. This popular myth also fails to acknowledge that there are more people living in slavery now than ever before in history.

I'm simply trying to dispel this naive, dangerously ignorant, ironically racist notion of slavery, so that people can hopefully have a greater understanding of human nature as a whole, and focus on fighting for people who are living in slavery right now, rather than just focusing on the legacy of slavery of 1 or 2 predominantly white nations from hundreds of years ago.

If you want to start a discussion about the Arab Slave Trade and reparations for it, feel free. But in the meantime, please don't derail discussions about one atrocity with a meta-discussion about every atrocity and how those atrocities rank amongst each other.

Why are you so anxious to shut down a broader discussion about the reality of human nature and slavery? Perhaps there is a painful reality of the human condition which you do not want to confront?

Go ahead, bring in the Arab slave trade, im pretty disgusted by that aswell, but the topic is the british.

And how kind of the British, like any major power with an advancing economy, seem to start focusing on human right just about the time slavery is offering more of an advantage to their adversaries. (But I'm not going to complain about that progress).

The topic is always British, European, or American. That's why it's valid to bring up other similar historical wrongs in this discussion without dismissing it as whataboutism. The "strange" focus on only the historical wrongs of a few particular groups of people impeaches the discussion of this sort of topic due to the obvious implicit bias that selects which groups should be held accountable.
