Was there ever a time when that was not the case? If it were impossible for the children of anti-science fundamentalists to constitute a sufficient and sane majority to protect science, we'd have almost certainly never gotten to where we are. That America, a country populated largely by those whose primary intent was the pursuit of religious fundamentalism, was ever the world lead in science and technology puts rather large holes in the "fundamentalists breeding will be the downfall of us all" argument. Similarly goes the concern about "dumb people breeding more/faster" necessarily leading to the dystopic future of IDIOCRACY. We can absolutely suffer a reversion to fundamentalism and/or a rise of proudly celebrated ignorance. There are plenty of historical examples of civilizations falling to those threats. I'm just saying that we also have plenty of data that it needn't necessarily go that way.
