Can’t justify it. PC makes us believe that Americans are the only people on earth who are guilty of slavery and black americans are the only people with slave ancestors in the history of the world. Look back 1000 years... 5000 years... slavery has been there. Hell, I am as white as white can be and I could be a decendant of a slave from 2500BC Egypt..
...and the Democrats are still the Party of slavers - even worse; but you have justified the Democrat Slaver Party by what you have stated. It's not PC, it's the Confederate flag's history - how it was birthed into existence in slavery; which is evil. It belongs to the Democrat Slaver Party - and should stay with the Democrat Slaver party.
