I'm not sure why people should respond to the suggestion seriously given that the VRA is about the community electing someone of their choice, not the race of the person elected;
No, the VRA states no such thing. A Black politician gerrymandered out of a mixed district would be a violation of the "regression" clause, while a White politician who was gerrymandered out the same district would have no standing even if in the primary the majority of Blacks voted for him, while the majority of Whites voted against him.
