The Republican party opposed slavery while the democrat party supported it. The democrat party started the KKK and was behind Jim Crow. The democrats opposed all attempts to make good on the promises America gave to them in the aftermath of the Civil War. When black people were given all the rights that anybody else had and all the racist laws on the books were expunged in 1960 Republicans did the right thing and walked away from the fight having done a job well as we always do.
Then democrats came around and lied to them including the lie that the two switched sides somehow- you know, like how cops and robbers switch sides every once in a while? LOL. And you started buying votes, causing the problems that they face to this day, promising to solve those problems, and then most importantly not solving those problems so that you can keep dangling that carrot in front of them. That's how you always work. The democrat is a snake in the grass and Malcolm X tried to warn black people but he got shot for it- by black people.
The truth is that the worst thing to ever happen to black people is abortion but a close second is the so-called "Civil Rights" movement. Martin Luther King, Jr. sold the blacks up the river in exchange for leadership and power. You think racist LBJ is a Civil Rights hero? Why not? He signed the Civil Rights (TM) act. Maybe catch that next time you're reading about LBJ, famous civil rights hero. LOL.
