There were Republicans in the south who also supported Jim Crow
Democrats from the north who were freedom riders
It was a north/south issue
No there wasn't. Republicans freed the slaves and democrats have spent the next 200 plus years putting them back in ghetto slave pens.
Yet, Republicans cannot point to a single piece of legislation in the last 50 years where they helped blacks or any other minority
Really? They emancipated them and They are the only reason the civil rights law was passed. Perhaps you should actually read history instead of making shit up.
Again you are over 50 years ago
Civil Rights was a product of northern Democrats and a Democratic president
Which one? The first one, the Civil Rights Act of 1957 was signed by Dwight Eisenhower (Republican) after it was proposed by Herbert Brownnell (Republican). The Act marked the first occasion since Reconstruction that the federal government undertook significant legislative action to protect civil rights.
The second one, the Civil Rights Act of 1964 was written by Senators Hubert Humphrey (D-MN) and Everett Dirksen (R-IL), and Representatives Emanuel Celler (D-NY), and William McCulloch (R-OH) and signed by Lyndon Johnson (Democrat). It would not have passed without 80% support of the Republicans in Congress.
Your attempt to re-write history to favor the Democrats fails.
