Leaving the Democrat Party’s slavery out of the discussion is also unacceptable omission.
In 1854 Democrats passed the Kansas-Nebraska Act which essentially made slavery legal in the USA. The Civil War followed shortly. Abe Lincoln freed the slaves, the Democrat party formed up their terror wing the KKK, to keep their political power in the south. So slavery is important, and discussing it and who did it is also important.
