My point is that just because these other nations didn't divide over the right to own/trade slaves and have a civil war over it - those governments very much embraced slavery - for both labor and trade.
The U.K. abolished slavery only 32 years prior to the U.S.
February 4, 1794 France abolished slavery. Reinstated it in 1802 and finally abolished slavery again in 1848.The Slavery Abolition Act 1833 (citation 3 & 4 Will. IV c. 73) was an 1833 Act of the Parliament of the United Kingdom abolishing slavery throughout the British Empire.
The abolition of all forms of slavery occurred in 1761 on mainland Portugal and Portuguese India through a decree by the Marquis of PombalAs a nation France had a lukewarm commitment to abolition. Under Napoleon - France reestablished slavery in 1802 along with the reinstitution of the "Code noir", prohibiting Blacks, mulattoes and other people of color from entering French colonial territory or intermarrying with whites.
These orders carried out by General Antoine Richepance brutally reinstituted slavery in the French Antilles in 1802. Thousands of people of color were killed in Guadeloupe alone as they fought to retain their freedom.
France as a country finally ended slavery in 1848.

I can go on with a fairly long list of countries whose government did incorporate the right to slave ownership into their laws or willfully condoned slavery for labor and trade. And slavery didn't end for some countries until nearly 20 years after the U.S. ended slavery in 1862...which of course divided the nation, created the Confederacy.The transatlantic slave trade was definitely outlawed altogether by Portugal in 1836, at the same time as other European powers, as a result of British pressure. Slavery within the African Portuguese colonies, however, would only be definitely abolished in 1869, following a treaty between United States and Britain for the suppression of the slave trade. In Brazil, which had become independent from Portugal in 1822, slavery was finally abolished in 1888.
From 1518 to the very latest date in which slavery was abolished - a lot of countries WERE GUILTY of slavery (for labor and trade) - BECAUSE - they all deemed Africans as inferior - almost animal like creatures only worthy for labor or trade.
In the end...I don't believe that state governments should be publicly displaying the Confederate flag - anywhere (schools, government buildings, state parks, state monuments, etc.) BUT - I don't believe government has the right to BAN the confederate flag from citizens or private businesses.
