I've heard people complain about the the world's overpopulation...
But never have I heard any of those people offer themselves or their own children in sacrifice for their idealistic goal.
We are all in this world together and it's up to all of us to accept and respect each other. Hatred and selfishness will only carry you so far, which isn't far at all in the grand scheme of things.
You, me, we... Love, acceptance, generosity. Keep focus on the good. We are in this together.
