So, the Confederate battle flag is the problem? Really?
157 years - Slavery existed under the British Union Jack in the British colonies of North America (1619-1776)
87 years - Slavery existed under the American Stars and Stripes (1776-1863) until the Emancipation Proclamation was issued on January 1, 1863
2 years, 4 months - Slavery existed under the various flags of the Confederate States of America from 1863 until the war’s end on April 9, 1865
STOP IT!
You’re trying to use logic and thought. This is an emotional issue, so you may only use knee jerk reactions and feelings.
Just over four years - February 1861 to roughly mid-June 1865.
Remember, the Emancipation Proclamation applied ONLY to those States the North did NOT control. It did not apply to Border States or Northern States. There was nothing keeping them from declaring it in 1861 in the States the North controlled.
But, slavery wasn’t really their issue.
FYI.
Hitler did the same thing with the swastika. It was a respected symbol going back to the Iron Age. Now Germany outlaws any public display and vigorously prosecutes anyone who manufactures something with the symbol—regardless of whether it is associated with Nazism or not.
You are providing facts to those with an average IQ of 76 in the city. Half of them will have a lower IQ than that. 1619? 1863? huh?
