It doesn't take special talents to reproduce--even plants can do it. On the other hand, contributing to a program like Emacs takes real skill. That is really something to be proud of.
Celebrating sexuality also spreads the myth that having a baby is something to be proud of, which fuels natalist pressure, which leads to pollution, extinction of wildlife, poverty, and ultimately mass starvation.
Perhaps the people who have decided to have no children should start making proud announcements, so as to set a better example. I could start. I'm sure everyone on this list will be glad to know I don't plan to reproduce myself.
