Anyone who has a real answer does not try to divert and focus on someone saying 'that was a million years ago' thinking they are scoring the only points they will get by being literal.
you betray your entire point by doing so.
She didn't say a million years ago, dummy.
She said 200 years ago, because that made more sense to her than 60 years ago, and she had no clue about the actual start of the farcical "racism party-swap theory".
A lot of Dems that were in their racist congress and the senate before 1964 just left in the 2000s, so the "late 60s" talking point doesn't make a lot of sense to her, right?
Eg, Exalted Cyclops/Dem Senator Byrd was in the senate from 1959 to 2010, right?
He was a KKK bigshot who ,not surprisingly, joined the official party of the KKK and then filibustered against the Civil Rights Act, but somehow Byrd and all the other racists stayed there and the racism magically swapped parties???? That's the actual swap theory

... Racism instantly or quickly transferred to the party that tried to get the civil rights act passed for 20 years up to that point, while all the senators and congressmen from each party stayed where they were
And how exactly did Exalted Cyclops Byrd go from "racist that was filibustering the 1964 Civil Rights Bill" to humanitarian? Was it a gift from God?
I will give Owly credit, because her theory makes more sense than the Dems' story, even though the GOP didn't officially exist yet at that point.
