I realize this might be in jest but I'll comment anyway since it seems our history is distorted when it comes to who did what.
The Indians, Andrew Jackson (considered the founder of the democrat party) signed the Indian relocation bill that was to begin the genocide that follows as it seems some tribes weren't so willing to give up their land.
Andrew Jackson was also a major slave owner who treated them horribly. Every slave owner in the south was a democrat BTW. Democrats overwhelmingly voted against the civil rights act of 1866. It was originally vetoed by president Andrew Johnson (a democrat) but congress over rode him.
The civil rights act of 1875 was also passed by a majority of republicans voting for it and a majority of democrats voting against it. It was signed into law president Grant, a republican.
Research the history of the woman's right to vote movement, republicans made that happen.
It was a democrat that put the Japanese in internment camps during world war 2.
It goes on and on.
