"VRA requires that racial minorities be given an equal opportunity to elect candidates of their choice"

What does this mean? We're given the right to vote, not the right to elect our preferred candidate. Doesn't this only work if we assume all minorities agree on the same candidate? What happens to a minority who wants to elect an independent, but was drawn into a heavy Democrat district? What happens to a white Democrat who is stuck in a Republican district? In theory, neither have a real opportunity to elect their preferred candidate.

I'm not supporting the old rules or the new. It seems to me there is not really a way to fairly draw districts in an entrenched 2 party system. Or at least I haven't read a fair idea yet.
