People feel hurt and lied to after decades of diligently studying a curriculum who's foundations turned out to be completely fake. Our mental garden must be protected from pests. Some pests even imitate benign bugs like ladybugs, in order to get in.
Imagine if tomorrow, it was announced that atoms and gravity don't exist, the motion of heavenly bodies don't even come close to Newton's laws, and physicists have just been lying so they can live off our tax dollars (but hey, we have a plan to one day start doing real physics experiments! Any day now, you'll see!).
I hope I'm not too dramatic, just felt defensive for some reason. If only there were a real science that could help me understand those feelings. Oh well, gotta keep the aphids out somehow.
