Are you seriously asking how having the views of different demographics represented actually helps? In any domain where ideas count having different views with different perspectives often enriches the discipline and leads to more breakthroughs and beneficial products for the rest of us. I point you to the civil rights movement and the fight to have more people included in the political process if you want an actual example of how having a demographic X in an industry Y can enrich the lives of everyone and make the world a better place and perhaps those different interests of those different people should contribute to the things that have such a large impact on our lives.
