Yes, as was the South... Besides, the Democrats were neutral on segregation at this time, while the GOP was mildly pro-civil rights.
The Democrats were not neutral, they were totally racist at this time. The Democrats were against all civil rights, favored (actually invented) Jim Crow laws, and used terror to keep Southern Blacks from registering. The southern Democrats wielded the filibuster to block any legislation that affected blacks. Even a Northern like Woodrow Wilson was a harsh racist with nothing but disdain for Blacks.
Given the long history of the Filibuster as a tool of Racists, its fairly ironic that the current crop of Democratic Senators are once again trying to block the majority with the Filibuster.
