Sounds like someone actually buys the Lost Cause Myth. https://en.wikipedia.org/wiki/Lost_Cause_of_the_Confederacy

Even the Daily Caller (hardly a progressive bastion) Fact checked your claim that Lee opposed slavery as False. http://dailycaller.com/2017/08/15/fact-check-did-robert-e-lee-oppose-slavery/

Everything I stated is generally accepted fact by most historians, save those who still cling to the Lost Cause. 

You trivialize Lee having his runaway slaves whipped with 50 lashes and then having their backs washed with brine by saying "whipping was a common punishment at the time."  

155 years ago many people held the "politically correct" standard that no humans should be slaves. https://en.wikipedia.org/wiki/Abolitionism_in_the_United_States 

If there were a "Civil War II", like the first one, it would be started by those who oppose equal rights for all or "political correctness" and they would once again be the losers.
