The “libs” were not the leading opponents of Jim Crow. The conservative old guard Republicans, like Taft, were also more likely to oppose Jim Crow and Civil Rights. FDR was completely in bed with Southern racists. Check out the roll call vote on the tougher version of the 1957 Civil Rights Act if you don’t believe me or any anti-lynching vote from the 1920s to the 1930s.

I meant to say that the Taft old guard Republicans were more likely to support Civil Rights and oppose Jim Crow.

That's a fair point. The social Dems who ran the South were the defenders of Jim Crow.
