tbh i'm less troubled by it than i once was
mainly because the more i talk to normal people the more i discover that creationism is far from being some sort of unique strain of irrational thought... it's merely one brand of irrational thought in a vast outlet-mall of made up BS that people subscribe to
e.g. most people i meet seem to believe jay-z and beyonce are puppets of the illuminati
or that aliens built the pyramids
or that 9/11 was and inside job
or that flouridation of water is an evil govt conspiracy
same with GMOs
questioning any of the above in working class circles gets you stared at like you have two heads, around here.
so i dunno maybe it's normal for people to believe dumb shit. skepticism seems like a relatively rare trait.
