I incorrectly assumed it would be obvious, but your second sentence in the post I replied to.
The justification of racism, slavery, and segregation by the Democratic party was based on the concept that Blacks were inferior. The origin of “White supremacy” in America. Essentially all institutions of racial oppression of blacks were originated by and maintained by Democrats (the political party formed by slave owners after the Revolutionary War). The Republican party opposed these policies. Furthermore:
- Almost all slave owners were DEMOCRATS.
- The DemocRAT party fought a civil war to preserve slavery.
- All of the Confederate soldiers and Generals were DemocRATS.
-All of the Confederate statues BLM had removed and destroyed were of DemocRATS.
- The Republican party fought the civil war to END slavery and succeeded in abolishing slavery.
- The Ku Klux Klan was part of the DemocRAT party and made up of DemocRATS.
- Segregation (Jim Crow laws) were imposed by the DemocRATS and opposed by Republicans.
