I like how every commenter after my post glazes over the fact I posted that North Carolina and other southern states are required by the federal government to create supermajority Democrat districts specifically to elect African-American candidates to Congress, and this in turn makes other districts that surround these districts more Republican. If you do not remove that requirement, that means Democrats in the rest of the state's districts would always be fighting uphill.
No because that is not true. That type of racial gerrymandering was not common until after the 1990 Census.
