Crusaders were curbstomped by Arabs for centuries largely becuase they kept advancing science and technology unimpeded by pseudo-religious traditions that prompted Crusaders to burn anyone caught with "heretical" Arab scientific works. By the Enlightenment, the shoe was on the other foot; Europe overcame dogmatic resistance and pushed the scientific envelope while Arabs condemned any discoveries threatening the status quo—and suddenly Europe went from being (literal) Arab cannon fodder to colonial masters of the world: Including the Muslim Mideast and North Africa. Children taught to deny biology at the dawn of genetic engineering will not "run into difficulties later in life when they start making their own world" because THEY WILL NOT MAKE THEIR WORLD: Intelligent educated people will, as they always have.

People run around dismissing our sinking shorelines because of Genesis says God promised to never again flood the world (though it does not say WE would not.) We are still "running into difficulties" THIRTY YEARS LATER because a US Interior Secy. declared our ability to forcibly SEIZE Mideast oil the modern equivalent of your beloved "Deus vult!" As rising populations and production strain Earths finite resources, the stalled US space program can never begin mining asteroids if we teach kids God created the rays of stars a million lightyears distant in situ 6000 years ago just to test our faith.

Believing falsehood is nearly always hobbling, falsehoods about the physical worlds "fundamental" nature especially so. Atop the central tower at a liberal indoctrination center I briefly attended is some seditious Marxists declaration that "ye shall know the truth, and the truth shall make you free." Scientific and other ignorance may not NOTICEABLY affect those lacking even indirect contact with the outside world, but right wing globalism is hellbent on proving holism despite conservative denial. The moment willfully backward people come into contact (and inevitable conflict) with others advanced enough to kill them with pinpoint accuracy by remote control from another continent, their "life" immediately becomes QUITE "difficult."
