This is one tiny facet of a society-wide problem that goes back millennia. How much progress can you expect in a few years? In the broader scope of things, I'd say we're making great progress.
But that progress has come through continuous effort, not from people saying, "Oh, honey, you should just accept that you can't vote. You'll never change it, so it's not rational to try."
I differ with that line of thought in that I don't think it's inevitable. Which is why I think it's so important to push for it. As the US Republican primary shows, there are plenty of people who'd like to roll back things from decades to centuries.
