I didn't ask for a wikipedia link to what the hoax/lie is.
You said Southern Republicans left the party en masse in protest over their party passing the Civil Rights Act (Your racist party was completely against it. We passed it in spite of you).
I asked you for the list of Southern Republican party members in the Senate and House that left the party en masse following the passing of the Act. IOW, I'm asking you to back up your claim with facts.
You can't provide the list. Because there isn't one.
You lied.
