Changing history

Look at how many slaves were in the British or French empires and they let them go without a war.

I'm not quite sure that's true, but I can't be arsed to look it up find anything to disprove you (at work y'see). Don't get me wrong, I don't think for a second wars were fought in order to abolish slavery in regards to both empires (never heard of that happening to be sure), but it seems that you're implying bloodshed wasn't spilled and that slaves were just lovingly freed without opposition in all other cases except for America? I dunno, I'm dubious of that.

Lovingly is probably not the right word. Abandoned to their own causes? The French abolished slavery in the midst of the french revolution, but it was sort of an afterthought. I don't see anybody claiming the French revolution as about slavery, even though it affected just as many slaves as the US civil war. Slavery was abolished in the British empire by an act of parliament, that was preceded by a series of judicial decisions. The Spanish abolished slavery through political means, although I'm not as familiar with them. I actually can't think of a case where there was a civil war over slavery.
