The second conversation was when Lincoln freed the slaves after a lot of white guys died in the Civil War.
Anglos haven't always been the top dog of the world. But Anglos were the first to use their global power to free not only the slaves in their lands, but also push for abolition in the nations they dealt with. Want to know why for the past century or so slavery is outlawed in almost the entire world?
Credit mainly goes to God. But since liberals insist He doesn't exist, then Anglos ought to get credit. Our Christian culture, particularly the Protestant culture Anglos adopted where even the masses were encouraged to learn and grow in their relationship with God, is what changed hearts and minds in the race that was on top of the world so that whites could use that influence to do world-wide abolition.
There's the "conversation" about race nobody wants to have.
