When I say "We will prove them wrong" I don't mean that in the "the arc of history bends toward justice" kind of passive inevitability. I understand that it's an active fight that never ends, and that there's no guarantee of success.
What I mean is that I believe that the people who employ a diversity of thoughts, opinions, beliefs, attitudes, lived experience, etc have always had, and will always have, a natural advantage. Those that can wield it will win out in the end.
The intolerant believe "purity" gives strength, but our modern world is built upon alloys toughened by adversity
