Bernie Sander's side has nothing of substance; he trots out socialism which is a total failure (except in all white countries), or which has resulted in the murder of millions by their own governments. So his party (which didn't support Lincoln) has to attack our past. My family has been in the U.S. since colonial times, and no one ever owned a slave. However, free blacks in the South and a few in the North did. So sort that one out, Bernie.
There are millions in slavery today, Columbus Dispatch just reported on some at chicken farms in Ohio, much of it still in Africa, much of it still in Muslim countries just as in the 17th and 18th century. Bernie's team-Democrat is supporting/advocating the deaths of the descendants of those who survived those terrible times. They are destroying their families with government transfers, tying them to the party plantation with "social justice" (just-us) programs.
Bernie's team even in my life time sent people to Congress who had been in the KKK, and who supported Jim Crow and voted against Republican civil rights efforts and anti-lynching laws. As recently as 2010, the Senate president pro tempore was former Exalted Cyclops Robert Byrd, D-W.V. If the South can't be trusted with a symbol, why trust the Democrats who are much, much closer to the problem--like the more recent 20th century? Living Democrats in glass houses had better stop lobbing rocks at dead Confederates. http://www.yourhoustonnews.com/courier/opinion/mona-charen-whitewashing-the-democratic-party-s-history/article_ae2148b7-7ce2-5c3b-abc0-0a45a57b13d7.html
