Jim Crow Laws : These laws were enacted in the late 19th & early 20th centuries by
"white Southern Democrat dominated state legislatures to disenfranchise & remove political & economic gains made by black people" during the Reconstruction period. It was Democrats that came up with all these "hate the black people" laws. They want blacks to stay on "their plantation & to never leave it" so that the Dems can stay in power.
Quote Joe Biden ..... you ain't black if you don't vote for me ..... I'll lie to you & I will keep you down.
