We can at least rest assured in this: sooner or later, Maslow's Hierarchy of Needs will wash this all away, and render such people as useless and irrelevant as they now believe children to be. A society that can facilitate people who concern themselves with gender equality and GLBT rights is a society that has too long been separated from the need for survival.
When they wreck it all, and survival is thrust back to the top of the list, their world comes to a harsh, cruel, sudden end, and in an instant, they'll know that everything they spent their lives caring about was an utter waste. So even if they take the rest of us down with them, I can take some small comfort in that.
