No, they are saying that your so-called idea has already been tried, but what actually happened was that <insert majority> who already had control set it up so <insert majority> could vote easily while <insert minority> could not. Could be race, could be something else. There is no such thing as an "objective test" for your case, because someone somewhere would need to determine it is objective. Who verifies that person, and who verifies the people who verify them?
